ABSTRACT:
Many cleaners, are extremely hard on many plastic products causing environmental stress cracking. Small household articles made from a polymer alloy of a clear brittle styrenic acrylate, a rubbery block styrene-diene copolymer, and a ductile styrene-diene polymer when exposed to such cleaners have significantly less environmental stress cracking.
