摘要
Thermoplastic copolymers of glutaric anhydride and (meth)acrylic esters are prepared free of acid groups by reacting a (meth)acrylic ester polymer with a secondary amine at from 150 DEG to 400 DEG C. Where the secondary amine is sufficiently volatile, any excess is removed at above 160 DEG C and below 26.6 kPA. The copolymers are amorphous, soluble, non-crosslinked and low acid. They may be blended with other polymers, formed into plastic articles, or swelled with cross-linking agents.
