Abstract:
A method of improving the stress crack resistance of an impact modified styrenic polymer comprising (a) combining about 95 to about 99.5 wt. % of an impact modified styrenic polymer with about 0.5 to about 5 wt. % of a polymer solution comprising about 25 to about 75 wt. % polyisobutylene and about 25 to about 75 wt. % of a polyolefin comprising one or more C2 to C12 alpha olefins.
