Polyamideimides Containing Carbonyl And Ether Linkages

Abstract

Polyamideimides of new class contain carbonyl and ether connecting groups. New polyamideimides more easily processable, stronger in tension, and more resistant to solvents (including water) than conventional polyamideimides. Improvements in mechanical and chemical properties attributable to semicrystallinity introduced into otherwise amorphous polymers by incorporation of carbonyl and ether linkages.
