Abstract

A transparent acrylic-based polymer composition has an increased resistance to alcohols, oils and fats. The polymer composition contains: (A) a copolymer of alkyl(meth)acrylates, aromatic vinyl monomer and unsaturated carboxylic acid anhydride; (B) a copolymer containing aromatic vinyl monomer and a vinyl cyanide monomer; and (C) a particulate core-shell type graft copolymer containing a butadiene-based core as a rubbery phase and a copolymer containing alkyl(meth)acrylates and, optionally, aromatic vinyl monomer as a hard phase. The components A and B form a polymer matrix and the particulate core-shell type graft copolymer C is dispersed in said polymer matrix.
