✦ Synopsis

New vinyl monomers having an isoxazole heterocyclic group were synthesized and were polymerized in dimethylformamide using azobisisobutyronitrile as a free radical initiator. The dependence of the rate of polymerization on monomer and initiator concentrations was determined, as well as the activation energy of polymerization. The addition of Lewis acid was found to a †ect the rate of polymerization. The prepared monomers were copolymerized with styrene, vinyl acetate, acrylonitrile and methyl methacrylate. The monomer reactivity ratios of all the systems were determined by linear and non-linear methods, and the Q and e values for the monomers were calculated by considering the four copolymerization systems in each case.
