The degradations have been studied by thermal volatilization analysis and thermogravimetry, with infrared and ultraviolet spectroscopic investigations of products. Under temperatureprogrammed heating conditions, PMVK first splits out water from adjacent side groups by a random process, giving a fuse
## Abstract Methyl vinyl ketone (MVK) was first used to successfully copolymerize with acrylonitrile (AN). This was achieved by using azobisisobutyronitrile as the initiator. Differential scanning calorimetry results of the degradation of AN/MVK copolymers in air are presented. The apparent activat
