On November 30, 1982, Van der Walle, H. B.; Bensink, T. published an article.Recommanded Product: 1985-51-9 The title of the article was Cross-reaction pattern of 26 acrylic monomers on guinea pig skin. And the article contained the following:

The cross-reaction pattern of acrylic monomers was investigated in 20 groups of animals sensitized to a different acrylic monomer. Animals sensitized to 1 monoacrylate tend to react to other monoacrylates. Reactions to corresponding or other monomethacrylates did not occur. Some reactions to di(meth)acrylates were observed A number of animals sensitized to 1 monomethacrylate reacted to some other monomethacrylates and monoacrylates. Reactions to di(meth)acrylates were observed Animals sensitized to di(meth)acrylates showed hardly any pos. cross-reaction. A universal screening allergen to detect acrylic monomer sensitizations does not exist. The composition of (industrial) products should be made accessible to the occupational dermatologist to prevent the undesirable situation in which a patient suspected of having an acrylic monomer sensitization must be tested with a large series of potent allergens to detect the real origin of the sensitization. The experimental process involved the reaction of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)(cas: 1985-51-9).Recommanded Product: 1985-51-9

On May 31, 1982, Van der Walle, H. B.; Delbressine, L. P. C.; Seutter, E. published an article.Recommanded Product: 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate) The title of the article was Concomitant sensitization to hydroquinone and p-methoxyphenol in the guinea pig: inhibitors in acrylic monomers. And the article contained the following:

Concomitant sensitization to hydroquinone and p-methoxyphenol occurred in sensitization experiments with acrylic monomers in guinea pigs. No relation between the concentration of the inhibitor in the monomers and the incidence of these concomitant sensitizations could be detected. Concomitant sensitization did not influence the cross reaction pattern of the acrylic monomers. The sensitizing potential of acrylic monomers is not influenced by the inhibitors, but some acrylic monomers seem to interfere with the sensitizing potential of the inhibitors. The experimental process involved the reaction of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)(cas: 1985-51-9).Recommanded Product: 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)

On November 30, 1987, Roberts, D. W. published an article.SDS of cas: 1985-51-9 The title of the article was Structure-activity relationships for skin sensitization potential of diacrylates and dimethacrylates. And the article contained the following:

Apparently conflicting guinea pig sensitization data on diacrylates and dimethacrylates, published by 3 groups of authors, are analyzed in terms of the relative alkylation index model. This model, correlating sensitization score with a combination of induction dose, chem. reactivity, and lipophilicity, enables the major discrepancies to be rationalized. The data provide a striking example of the overload effect, in that some of the diacrylates have failed to show sensitization when tested at high induction doses, but are revealed as strong sensitizers when tested by other authors at lower induction doses. The experimental process involved the reaction of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)(cas: 1985-51-9).SDS of cas: 1985-51-9

And the article contained the following:

One of the urgent tasks in understanding endocrine disruptors (EDs) is to compile a list of suspected substances among the huge number of chems. by using the screening test method. We developed a simple and rapid screening method using the yeast two-hybrid system based on the ligand-dependent interaction of nuclear hormone receptors with coactivators. To date, we have tested the estrogenic activity of more than 500 chems. including natural substances, medicines, pesticides, and industrial chems. Sixty-four compounds were evaluated as pos., and most of these demonstrated a common structure; phenol with a hydrophobic moiety at the para-position without bulky groups at the ortho-position. These results are expected to facilitate further risk assessment of chems. The experimental process involved the reaction of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)(cas: 1985-51-9).COA of Formula: C13H20O4

On January 31, 1983, Van der Walle, H. B.; Waegemaekers, T.; Bensink, T. published an article.HPLC of Formula: 1985-51-9 The title of the article was Sensitizing potential of 12 di(meth)acrylates in the guinea pig. And the article contained the following:

The sensitizing potential of 12 di(meth)acrylates was investigated in the Guinea Pig Maximization Test and Freund’s Complete Adjuvant Test (FCAT). In these tests, the same (molar) concentration was used for intradermal induction. Dimethacrylates were moderate to strong sensitizers in the guinea pig. In diacrylates, no sensitization to diethylene glycol diacrylate  [4074-88-8] was observed 1,2-ethanediol diacrylate  [2274-11-5] And 1,6-hexanediol diacrylate  [13048-33-4] sensitized a number of animals. The challenge reaction pattern of the FCAT with 1,4-butanediol diacrylate  [1070-70-8], neopentanediol diacrylate  [2223-82-7] and 5-pentanediol diacrylate  [36840-85-4] differed form that commonly observed with sensitizers. Pos. reactions were seen only to the maximum nonirritant concentration at 24 h in the challenge at day 21. At 48 h and in the 2nd challenge at day 35, the reactivity had decreased or disappeared. This different reaction pattern made it difficult to classify these monomers with certainty as sensitizers. In most of the FCATs, a decrease in reactivity in successive challenges was found. Possible explanations for this decrease and for the different challenge reaction patterns of some diacrylates were discussed. The skin irritant capacity of di(meth)acrylates was estimated after 1 open application. Diacrylates were very strong irritants on guinea pig skin. Dimethacrylates were weak irritants. The experimental process involved the reaction of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)(cas: 1985-51-9).HPLC of Formula: 1985-51-9

Application of the theory of R. Kubo and K. Tomita (1954) to correlation times for α- and β’-relaxations in oligoester acrylates [1,3-propanediol bis(2-hydroxyethyl carbonate) dimethacrylate [60028-80-0], neopentylglycol bis(2-hydroxyethyl carbamate) dimethacrylate [54547-48-7], 2,2-bis(chloromethyl)-1,3-propanediol bis(2-hydroxyethyl carbonate) dimethacryalate [54547-50-1], neopentyl glycol dimethacrylate [1985-51-9]] and the corresponding polymers determined by NMR gave relatively low correlation values when compared with data from dielec. and mech. measurements.

Volkov, G. U.; Boichuk, B. G. published an article in 1988, the title of the article was Kinetic features of the oxidative copolymerization of methacrylic esters with oligomeric piperylene rubber in a film.HPLC of Formula: 1985-51-9 And the article contains the following content:

The ratio (R) between consumption rates of double bonds and O was monitored during oxidative polymerization of piperylene rubber-dodecyl methacrylate (I) or – neopentyl glycol dimethacrylate (II) coatings to elucidate the roles of homopolymerization and copolymerization with O in this reaction. The R was ∼1-2 during almost entire period of polymerization, indicating that the homopolymerization somewhat prevailed over the copolymerization An increase in R toward the end of polymerization of coatings containing ≤35% I was attributed to morphol. changes that transfered the process into diffusion regime. A decrease in R in the beginning of polymerization of coatings containing II was ascribed to the decomposition of II associates The latter coatings showed a sharp increase in R toward the end of polymerization, due to increased consumption rate of vinyl bonds. The activation energies of oxidative polymerization processes were determined The experimental process involved the reaction of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)(cas: 1985-51-9).HPLC of Formula: 1985-51-9

Volkov, G. U.; Rudnaya, G. V.; Berent, N. I. published an article in 1988, the title of the article was Crosslinking and degradative transformations in a film during oxidation.Category: esters-buliding-blocks And the article contains the following content:

Oxidative crosslinking of model coatings from piperylene rubber SKP-N and dodecyl methacrylate (I) or butyrate proceeded via formation of O-containing groups; the degradation of SKP-N prevailed and no significant polymerization of I was observed Low d.p. of I was attributed to degradative chain transfer from alkyl and, especially, peroxide radicals of I on SKP-N with formation of stable allyl radicals. The crosslinking of coatings from SKP-N and neopentyl glycol dimethacrylate (II) was oxidative in the top layer and was due to homopolymerization of II in the bottom (adjacent to substrate) layer when coatings contained a small amount of II. The homopolymer of II was insignificantly in thin coatings, owing to degradative chain transfer, but increased in the coatings with thickness 60-70 μ. Increasing the content of II ≥65% resulted in oxidative crosslinking throughout the film, apparently because of the increased O diffusion. The experimental process involved the reaction of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)(cas: 1985-51-9).Category: esters-buliding-blocks
