ABSTRACT:
Thermoplastic, non-crosslinked polymer compositions having glutaric anhydride units of the formula: ##STR1## wherein R represents CH.sub.3 or H, process for imidizing said compositions, the resultant imide polymers which are free of methyl imide units, and process of devolatilizing an acrylic or methacrylic acid-containing polymer in an extruder to the corresponding anhydride, and then introducing a reactant selected from the group consisting of ammonia, ammonia generators, primary amine, and primary amine generators.
