Abstract: Macroporous polyvinylamine resin was prepared by Hofmann degradation of poly-acrylamide.The factors influence the reaction were discussed.The results show that the degradation reaction of macroporous polyacrylamide resin at 0℃ as well as at -10℃ can happen.As the increase of Rfrom 13 to 20, the conversion increased.When r was 1.2 and Rwas 19, the best conversion was obtained.

Key words: Hofmann degradation, Resin, Polyacrylamid(PAA)
