Suzuki, Shiro published an article in 1981, the title of the article was Preparation of hard crown and bridge resins with new composite fillers.Safety of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate) And the article contains the following content:
Composite fillers were prepared with several polyfunctional monomers and 20 mμ hydrophobic colloidal SiO2 to improve the properties of the dental resins. Thus, 100 parts 6:4 mixture of triethylene glycol dimethacrylate and bisphenol A dimethacrylate, neopentyl glycol dimethacrylate, trimethylolpropane trimethacrylate (I) ethylene glycol dimethacrylate, or a 1:1 mixture of 2,2-bis[4-methacryloxypoly(oxyethylene)phenyl]propane(II) and dimethacryloxyethyl trimethylhexamethylene diurethane(III) was mixed with 50 parts SiO2 and 0.5 parts Bz2O2, followed by polymerization 20 min at 100-120°, and ball milled to give a filler. The filler(120 parts) was mixed with 100 parts of matrix monomers, 0.6 part Bz2O2, and 16.7 parts SiO2, followed by polymerization 20 min at 100-120° in a Teflon mold under pressure. Mech. properties of the test specimens were best with the filler prepared with I. Combination of the filler prepared from I and the matrix monomers, the 1:1 mixture of II and III, gave a product with the highest compressive strength, transverse strength, and the Brinnell hardness and the lowest thermal expansion coefficient The experimental process involved the reaction of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)(cas: 1985-51-9).Safety of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)
