Copolymers of N-vinyl-2-pyrrolidone and condensation polymers

Аннотация

The results of study on the radical polymerization of N-vinyl-2-pyrrolidone containing a dissolved polyimide, an aromatic polyamide, and a polyarylate are presented. Formation of both poly(vinylpyrrolidone) homopolymer and its copolymers with the above condensation polymers is detected. The obtained (co)polymers differ from poly(vinylpyrrolidone) in heat resistance and solubility. It was shown that polyimides can be prepared in a N-vinyl-2-pyrrolidone medium followed by in situ polymerization of the latter.
