ABSTRACT:
Disclosed is a resin composition which comprises (a) 5 to 95% by weight of a styrene-based polymer having a syndiotactic configuration, (b) 95 to 9% by weight of a thermoplastic resin having at least one polar group selected from a carboxyl group, a hydroxyl group and an amino group at the terminal; and (c) 0.01 to 15 parts by weight of a styrene-based copolymer obtained by copolymerizing a styrene compound with a vinyl compound having an epoxy group or a styrene-based copolymer obtained by copolymerizing a styrene compound with an .alpha.,.beta.-unsaturated carboxylic acid anhydride based on 100 parts by weight of the aobve components (a) and (b). The composition exhibits no laminar peeling and has an excellent appearance because affinity and dispersibility of the styrene-based polymer and the thermoplastic resin are improved, and a polystyrene-based resin composition improved in mechanical strength can also be obtained without using a complicated process.
