Kinetic study of free radical copolymerization of dodecyl methacrylate and styrene using diperoxide initiator

In this study kinetics of the free radical copolymerization of styrene and dodecyl methacrylate in xylene solution using diperoxide initiator, up to high conversions, was investigated. Kinetic results and structural properties of the synthesized polymers were compared with values obtained for homopolymerization and copolymerization systems initiated with conventional monofunctional initiator. It was established that higher polymerization rates can be achieved by using diperoxide initiator while maintaining high values of molecular weight and a relatively narrow polydispersity index. However, in copolymerization systems with higher mole fractions of dodecyl methacrylate in initial feed, the fall of diperoxide initiator efficiency was observed.
