Abstract

PURPOSE: To obtain a syrup capable of giving cured articles having improved weatherability, free from heat discoloration, by partly polymerizing a mixture of an acrylate or methacrylate monomer with copolymerizable monomers in the presence of a thiol compound, and by treating the partial polymer with a basic organic compound.
CONSTITUTION: 100 Parts by wt of a blend comprising (A) 50wt% or more of an acrylate or methacrylate compound or its mixture with monomers and (B) 50wt% or less of a monomer copolymerizable with (A) is polymerized partly with (C) 0.01W7.0 parts by wt of a thiol compound in the presence or absence of a catalyst, and the polymerization is stopped before gelation. 0.0002W4.0 parts by wt of a basic organic compound is added to 100 parts by wt of the polymer wherein 0.5wt% or more of the unreacted acrylate compound is present.
