ABSTRACT:
Process for preparing halogenated rubbery copolymers of ethylene, at least one other .alpha.-alkene, dicyclopentadiene and optionally one or more other polyenes is disclosed, wherein the copolymer is halogenated in the substantially undissolved or solid state with molecular halogen at a temperature of between -30.degree. and +80.degree.C. The halogenated copolymers produced by the process of the present invention may be covulcanized with strongly unsaturated rubbers to yield products which have excellent physical and mechanical properties, with reduced vulcanization times. The vulcanizates are suited for numerous applications including, for instance, car tires.
