On May 31, 1982, Suzuki, Shiro; Nakabayashi, Nobuo; Masuhara, Eiichi published an article.Product Details of 1985-51-9 The title of the article was The evaluation of new dental resins prepared with polyfunctional methacrylate monomers. And the article contained the following:

The combinations of several composite fillers and dimethacrylates for crown and bridge resins were investigated. The composite filler prepared from trimethylolpropane trimethacrylate (TMPT) markedly improved the mech. and phys. properties of crown and bridge resins. The enhancement of the mech. and phys. properties is due to the highly crosslinked structure which is developed with the use of the reactive composite filler which copolymerizes with the matrix monomer. The combination of the 2,2-bis(4-methacryloxypolyethoxyphenyl)propane  [41637-38-1], dimethacryloxyethyl(trimethylhexamethylene diurethane) [41137-60-4] comonomer and the TMPT composite filler exhibited the maximum compressive strength, transverse strength, and Brinell hardness, and min. abrasion loss and thermal expansion. This hard resin was superior to the resins currently available for clin. use. The experimental process involved the reaction of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)(cas: 1985-51-9).Product Details of 1985-51-9

This in vitro study evaluated the wear effects of five posterior denture tooth materials on human enamel. The tooth specimen was cusp shaped and enamel specimen was formed as a 10 × 10 × 5 mm plate. All material-enamel combinations were tested using a machine designed to produce sliding contact 20 × 104 times at 60 cycles min-1 and a 4-mm sliding distance per stroke in the bucco-lingual direction under a load of 1 kg. Wear anal. was measured as the total height loss of each combination. In addition, the surface roughness (Ra) of each worn specimen was also evaluated. The least total height loss occurred with poly(Me methacrylate) (PMMA) enamel pair, and the greatest did with porcelain (Po)-enamel pair. The lowest compound Ra value was measured in high-strength resin (HR)-enamel pair, and the highest in Po-enamel pair. The best combination is PMMA-enamel, and the poorest combination is Po-enamel. The experimental process involved the reaction of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)(cas: 1985-51-9).Synthetic Route of 1985-51-9

On April 30, 1983, Kumakura, Minoru; Kaetsu, Isao; Suzuki, Mieko; Adachi, Shoichi published an article.Safety of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate) The title of the article was Immobilization of antibodies and enzyme-labeled antibodies by radiation polymerization. And the article contained the following:

Immobilization of antibodies and enzyme-labeled antibodies on polymeric supports by radiation polymerization at low temperatures was studied. The antibody activity was not affected by a radiation dose below 8 MR and low temperatures Immobilization of peroxidase-labeled α-antirabbit IgG, antiperoxidase, peroxidase, and anti-α-fetoprotein was carried out with hydrophilic and hydrophobic monomers. The activity of the immobilized enzyme-labeled antibody polymer membranes varied with the thickness of the membranes and increased with decreasing membrane thickness. The activity of the immobilized antibody particles was varied by particle size. Immobilized anti-α-fetoprotein particles and membranes can be used for the assay of α-fetoprotein by the antigen-antibody reaction, such as a solid-phase sandwich method with high sensitivity.

On December 31, 1996, Satou, N.; Morikawa, A.; Ohmoto, K.; Urabe, H.; Shintani, H.; Wakasa, K.; Yamaki, M. published an article.Reference of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate) The title of the article was Adhesion of streptococci to saliva-coated and uncoated composite-based resins. And the article contained the following:

This study was designed to evaluate the bacterial adhesion to 5 types of exptl. composite-based resins and a com. composite resin used as a control. Physicochem. surface characteristics of composite resins with and without an artificial saliva coating were measured. The relationship between the numbers of adhering cells (Streptococcus sanguis, S. mutans and S. sobrinus) and surface characteristics was analyzed. The values of contact angles and the number of adhering cells were small with saliva coating. S. sanguis ATCC 10557 showed a pos. correlation with the contact angles of uncoated resins, whereas no relationship was observed for saliva-coated resins. With S. mutans, the cell numbers adhering to resins correlated strongly with the values of zeta potential of resins for either saliva coating or uncoated. Elec. repulsion forces had a strong contribution to adherence of cells such as S. mutans and S. sobrinus which show a high absolute zeta potential.

On November 30, 2008, Imamura, Soichiro; Takahashi, Hidekazu; Hayakawa, Iwao; Loyaga-Rendon, Paola G.; Minakuchi, Shunsuke published an article.Synthetic Route of 1985-51-9 The title of the article was Effect of filler type and polishing on the discoloration of composite resin artificial teeth. And the article contained the following:

In this study, the effects of filler type and polishing on the discoloration of composite resin artificial teeth were examined Four types of exptl. resins were prepared: one was a matrix resin, while the others were composite resins containing three different types of fillers (nano-sized silica filler with or without silanization, and prepolymerized filler). Specimens were immersed in distilled water, coffee, red wine, or curry. Color change after immersion was measured using a colorimeter. Color difference values (ΔE) and changes in translucency parameter (ΔTP) were statistically analyzed using three-way ANOVA and Tukey’s comparison. On the influence of the polishing factor, statistically significant differences were neither observed in Δ E nor Δ TP between polished and non-polished tooth surfaces. On the contrary, the influences of filler type and discoloration medium, and their interaction thereof, were significant. With unsilanized filler, the Δ E value of composite resin artificial teeth was significantly increased. The experimental process involved the reaction of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)(cas: 1985-51-9).Synthetic Route of 1985-51-9
