N-Substituted dimethacrylamide

Five-membered ring imides in cyclopolymers of N-substituted dimethacrylamides such as PSPDM can be hydrolyzed to amic acids under moderately basic conditions. The resulting N-substituted amide is extremely resistant to basic hydrolysis. Consequently, this basic hydrolysis approach can still not be employed for the preparation of head-to-head poly(methacrylic acid). 

Radical polymerizations of N-substituted dimethacrylamides are known to proceed with complete cyclization to form a five-membered ring as a main repeating unit and a six membered ring as a minor repeating componentVarious mechanisms have been proposed for the cyclization polymerization of unconjugated dienes Kodaira et al. examined by ESR the cyclization polymerization of N-substituted... 

Imide Hydrolytic Stability of TV-Substituted Dimethacrylamide Cyclopolymers Poly [ N- (4-sulfophenyl) dimethacrylamide]... 

The hydrolysis of PSPDM under the basic conditions studied was unanticipated in light of the hydrolyti stability of N-substituted poly(dimethacrylamides) studied by Vogl, Otsu, and coyyprkers.
