On May 31, 1984, Hirabayashi, Shigeru; Nasu, Ikuyo; Harashima, Ikuro; Hirasawa, Tadashi published an article.Name: 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate) The title of the article was Studies on dental methacrylic resins. Part 9. On composition of heat-shock, pour-type and self-curing denture base resins. And the article contained the following:
The compositions of the powders and the liquids of 9 heat-curing, 3 heat-shock, 6 pour-type and 1 self-curing denture base resins were analyzed by pyrolysis gas chromatog., HPLC and IR spectroscopy. The polymer powders of 14 resins investigated were granular poly(Me methacrylate) (PMMA) [9011-14-7]. However, 2 pour-type and 1 self-curing resin used Et methacrylate-Me methacrylate polymer [25685-29-4] as the polymer powder. In 1 heat curing resin, the powder mixture of which showed a long dough-stage, the polymer blend consisted of PMMA and Bu methacrylate-Me methacrylate polymer [25608-33-7] and another heat-curing resin, called impact-resistant resin used PMMA containing a small amount of styrene-butadiene rubber, as the polymer powder. The average mol. weights and the average grain sizes of these polymers were 6∼110×104 and 15∼80 μm, resp. The average mol. weights and the grain sizes of the polymers of the pour-type and self-curing resins were smaller than those of the heat-curing and heat shock ones. The liquids of resins investigated all contained Me methacrylate [80-62-6] as main component, and crosslinking agent except for one material. Ethylene glycol dimethacrylate [97-90-5], 1,3-butanediol dimethacrylate (1,3-BuDMA) [1189-08-8], 1,4-butanediol dimethacrylate [2082-81-7], and (or) trimethylolpropane trimethacrylate (TMPT) [3290-92-4] were used as crosslinking agents, and these contents were almost 3∼5%, but the liquid of one material which had a long dough-stage contained 21% of 1,3-BuDMA. For 1 pour-type and 1 self-curing resin, the unique redox initiator system, namely trimethylbarbituric acid [7358-61-4]-(Cu2+) (Cl-) might be employed instead of Bz2O2-amine. The experimental process involved the reaction of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)(cas: 1985-51-9).Name: 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)
