Abstract
PURPOSE:To obtain titled resin without lowering its transparency and surface luster, by grafting first a mixture of a crosslinking monomer and methyl methacrylate and, then, methyl methacrylate onto an acrylate ester elastomer of a specified double structure. CONSTITUTION:Titled resin is obtained by polymerizing (c) 5-100pts.wt. monomer mixture consisting of (i') 80-99.9wt% methyl methacrylate (hereinbelow abbreviated as MMA) and (ii') 0.1-10wt% polyfunctional crosslinking monomer containing at least two C-C double bonds in the presence of 100pts.wt. double-structured acryl elastomer containing, in its interior, (A) 5-50pts.wt. rigid cured resin containing at least 80wt% of MMA and containing, in its exterior layer, (B) 95- 50pts.wt. polymer consisting of (i) 69.9-89.9wt% of 1-8C alkyl acrylate ester, (ii) 30-10wt% styrene or mixture thereof with a styrene derivative, and (iii) 0.1- 10wt% polyfunctional crosslinking monomer containing at least two C-C double bonds and, after addition of (D) 5-1,000pts.wt. MMA (D/C=0.5-200), polymerizing the mixture.
