Abstract
Abstract A thermoplastic resin having high impact strength and a process for producing such thermoplastic resin, the thermoplastic resin being obtained by polymerizing a homogeneous mixture comprising, (a) chlorinated polyethylene; (b) acrilonitrile; and (c) styrene. Also, a thermoplastic resin composition having a high impact strength comprising the thermoplastic resin set forth above in admixture with a polyvinyl chloride resin and optionally a minor amount of polymethylmethacrylate.

A thermoplastic resin composition having high impact strength comprising: A. a thermoplastic resin obtained by polymerizing a homogeneous mixture consisting of (a) chlorinated polyethylene having a degree of chlorination of 10 - 50 percent by weight, (b) acrylonitrile and (c) styrene, the range of weight ratio of said (a) to (b) plus (c) being from 10:90 to 80:20, and the range of weight ratio of said (b) to (c) being from 10:90 to 90:10, B. a polyvinylchloride resin having a degree of polymerization of 500 - 2,000, and C. polymethyl methacrylate, said A, B and C being mechanically blended in a weight ratio of A to B of 10:90 to 80:20, and C in an amount of 5 - 30 parts based on 100 parts of combined weight of A and B.
