Abstract
An alkyl acrylate copolymer comprises 60 to 99.5 wt. % of a C.sub.2 -C.sub.12 alkyl acrylate component, 0.1 to 10 wt. % of a polyfunctional monomer component having one or more conjugated double bond and one or more non-conjugated double bond and 0 to 35 wt. % of a comonomer component. A thermoplastic resin composition comprises 97 to 70 wt. parts of a rigid thermoplastic resin and 3 to 30 wt. parts of the alkyl acrylate copolymer.
