Photopolymerization initiated by charge-transfer complex: VIII—Effect of solvent

Abstract

Polymerization of methyl methacrylate in visible light was studied at 35°C using quinaldine-chlorine (QU-Cl₂) charge-transfer complex as the photoinitiator in the presence of several solvents. Analysis of kinetic and other data indicate that the polymerization proceeds via a radical mechanism and the termination is initiator dependent. Chain termination via degradative chain (initiator) transfer appears to be significant here.
