Abstract
PURPOSE: A diacrylate or dimethacrylate bearing aromatic rings is polymerized at low temperature and the resultant polymer is combined with a monomer copolymerizable with the polymer to prevent the gelation and gives a liquid prepolymer of high storage stability and constant properties kept for a long period of time.
CONSTITUTION: (A) A polymer that is obtained by low-temperature polymerization of a diacrylate or dimethacrylate bearing aromatic rings is combined with (B) at least one of unsaturated monomers copolymerizable with the above monomer or (C) a mixture of at least one of component A monomer and at least one of monomers of component B. An example of component A is a compound of formulaI(R1 is H, methyl; R2 is formula II, or formula III; X is Cl, Br; Y is -0-, -SO2-, -CH2-; a, b are 0W4; l is 0, 1; m, n are 0W4) such as 2,2-bis(4-methacryloxyethoxy-3,5-dibromophenyl)propane and that of component B is acrylic or methacrylic ester or styrene.
