Abstract

2 - Methyl - 1,3 - pentadiene is copolymerized with 4-methyl-1,3-pentadiene using a catalyst which is the reaction product of a vanadium halide or oxyhalide with an aluminium trialkyl or aluminium alkyl halide. The preferred catalyst components are selected from vanadium trichloride and vanadium oxytrichloride and aluminium triethyl, triisobutyl and trihexyl. Normally 75 mol. per cent of 2-methyl-1,3-pentadiene and 25 mol. per cent of 4-methyl-1,3-pentadiene are used. Preferably the polymerization is carried out in a diluent, preferably n-heptane. The copolymer may be vulcanized.
