Abstract

PURPOSE: To obtain thermoplastic resin particles of a uniform small grain size by the reaction of a styrene-maleic anhydride copolymer, a binding monomer, and a polymerization catalyst, which have been dissolved in a vinyl aromatic monomer and then suspended in an aqueous medium.
CONSTITUTION: A styrene-maleic anhydride copolymer having 15W30wt% of maleic anhydride and average polymerization degree of 500 or more, a compond of the formula RS (wherein X is a functional group reactive to dicarbonyloxo group and R is an aliphatic residue with one double bond), and a polymerization catalyst are dissolved in a vinyl aromatic monomer, and then the solution is suspended in an aqueous medium and then put into a reaction to obtain a thermoplastic resin containing 2W10wt% maleic anhydride. During or after the aforesaid reaction, a foaming agent is added with the purpose of obtaining expansible thermoplastic resin. The preferred amount of the compound of the formula RX is 0.1W20mol%, preferably 0.2W10mol%, on the basis of maleic anhydride present in the copolymer.
