ABSTRACT:
Polymers having a tertiary amide group, particularly homopolymers and copolymers of vinylpyrrolidone, are modified by treatment with reactive acid chlorides, the amide functions being converted into amide chlorides. These modified polymers are reactive intermediates and may be used to obtain a variety of new polymeric substances.
