摘要

Abstract

The pyrolysis reaction of acrylonitrile(AN)/N-vinylpyrrolidone(N-VP) copolymer in air was studied with DSC. The apparent activation energy of pyrolysis reaction of copolymer was calculated by the Kissinger method. The effect of different copolymerization conditions on the apparent activation energy of copolymer was discussed. It was found that with an increase of DMSO concentration in mixture solvent，the degradation apparent activation energy rose rapidly. When the weight ratio of N-VP/AN was less than 5/95

the apparent activation energy of degradation reduced quickly with the comononer N-VP concentration rising

and when the ratio was more than 5/95

the apparent activation energy became almost constant. When the copolymerization temperature rose

the apparent activation energy also increased.
