IMPACT MODIFIED STYRENIC POLYMERS WITH IMPROVED STRESS CRACK PROPERTIES
摘要
<p>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.</p>
