Abstract

PURPOSE: To obatin a thermoplastic resin having excellent heat resistance and good sheet moldability by the polymerization of a mixture of a styrene-maleic anhydride copolymer resin and a vinyl aromatic monomer in the absence of solvent.
CONSTITUTION: A thermoplastic resin containing 2W10wt% of maleic anhydride is obtained by the polymerization of an uniform mixture of a styrene-maleic anhydride copolymer of an average polymerization degree of 500 or more and a vinyl aromatic monomer in the absence of solvent. In this case, when the styrene-maleic anhydride copolymer having an average polymerization degree of 500 or less or 4,000 or more is used, the use of the former lowers the mechanical strength of the resin molding obtained, whereas the use of the latter makes the resin obtained brittle. Therefore, the copolymer of the average polymerization degree of 4,000 or less is preferable.
