vinyl chloride resin composition having a high resistance to shocks and to atmospheric agents

摘要

A high impact-resistant vinyl chloride polymer resin composition having an excellent weather resistance which is composed of from 3 to 30 weight parts of a modified MBS resin obtained from addition-reaction of an alkyl mercaptan containing from 2 to 20 carbon atoms with a butadiene-styrenemethyl methacrylate resin, and from 97 to 70 weight parts of a vinyl chloride resin.
