Bicyclo [2.2.1] hepta-2,5-diene, the reaction product of acetylene and cyclopentadiene, and vinyl chloride readily copolymerized by a novel mechanism, to form copolymers containing the nortricyclene group whose softening points rapidly increase with increasing nortricycl one concentration. For each weight per cent copolymerized bicycloheptadiene, the softening point of the vinyl resin is increased about 1°C, making it the most effective comonomer known for this purpose. At the same time increasing nortricyclene concentration disrupts polymer crystallinity, lowers the resin's melting point, and hence its processing temperature, by about 3°C for each weight per cent copolymerized.
