On the Homogeneous Polymerization of Acrylonitrile

IV. The Polymerization Initiated by Organic Peroxides in Dimethylsulfoxide

Abstract

Several organic peroxides were used as the initiator in the homogeneous polymerization of acrylonitrile (AN) in dimethylsulfoxide (DMSO), and lauroyl peroxide (LPO) was found to be effective. Lauroyl peroxide-dimethylaniline (DMA) system has been shown to be the most favorable redox initiator in this work. In this case the rate and the degree of polymerization could be represented by the following equations respectively.
The rate of polymerization:

The degree of polymerization:
