MONOVINYL AROMATIC MONOMER-ACRYLONITRILE COPOLYMER AND PREPARATION THEREOF

Improved monovinyl aromatic monomer-acrylonitrile copolymers are prepared by mass 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, hav...

More Information
Summary:Improved monovinyl aromatic monomer-acrylonitrile copolymers are prepared by mass 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. These copolymers are especially desirable for fabricating food containers. 17,703B-F
