Studies on graft copolymerization of cyclohexyl methacrylate onto 1,2-polybutadiene
Abstract
The free radical grafting of cyclohexyl methacrylate (CMA) onto 1,2-polybutadiene (1,2-PBD) in benzene solution at 60°C was studied. The graft copolymer was characterized by IR, NMR, DSC, and intrinsic viscosity measurements. The polymerization of CMA shows normal kinetic behavior when the PBD concentration is kept below 1.0 monomer mol/L. The rate of grafting was determined at different reaction times, monomer concentrations, initiator concentrations, backbone concentrations, temperatures, and concentrations of the zinc chloride additive. The performance of the graft copolymer used as adhesive was also investigated for bonding of PVC/PVC film.
