Abstract

Moldable compositions which comprise a high molecular weight nonequimolar copolymer of an ethylenically unsaturated dicarboxylic acid or its derivative, and at least one copolymerizable monomer and, a surface gloss enhancing agent selected from the group consisting of amides or N,N-dimethylamides of linear and saturated or unsaturated fatty acids containing 16 or more carbon atoms and low molecular weight copolymers of styrene and maleic anhydride, facilitate the production of molded articles exhibiting improved surface gloss.
