Abstract
Polymer blends are provided comprising a glassy thermoplastic polymer having a glass transition temperature above ambient conditions, e.g., normal room temperature and between 0.1 and 4.0 weight percent of a rubbery polymer having a glass transition temperature below ambient temperature conditions, e.g., normal room temperature based on the weight of the blend. The blends can be produced by solution casting or by coagulation from solution followed by flocculation.
