ABSTRACT:
Improved monovinyl aromatic monomer-acrylonitrile copolymers are prepared by polymerizing at temperatures above 80.degree. C in the presence of certain free radical initiators, the resultant polymers are prepared at high rates of conversion, have relatively high heat distortion temperatures, have a low oligomer content and generate relatively little additional acrylonitrile under fabrication conditions.
