Notes:
Kinetics of vinyl polymerization of acrylonitrile initiated by the redox system tartaric acid-V5+ have been investigated in aqueous sulfuric acid in the temperature range 30-40°C. The rates of polymerization and V5+ disappearance and the chain lengths of polyacrylonitrile were measured. From the results it is concluded that the polymerization reaction is initiated by an organic free radical arising from the V5+-tartaric acid reaction with termination by V5+ ions. A suitable kinetic scheme has been proposed, and the various rate and energy parameters were evaluated.
