Abstract
The charge transfer initiated polymerization of acrylonitrile by 2,4-dinitrophenylhydrazine (DNPH) and Cu2+ in the presence of carbon tetrahalide was studied in dimethyl sulphoxide at 60°C. The rate of polymerization became maximum when the mol ratio of [DNPH] to [Cu2+] was 4:1. The polymerization was inhibited after a very short period when the above ratio was 2:1, mainly due to the liberated bromine. A suitable mechanism for the experimental observation is proposed.
