The polymerization of 4-vinyl-1-cyclohexene (4VCHE) with Ziegler-Natta catalysts was studied. The polymerization of 4VCHE by the vinyl group took place with TiCl3-aluminum alkyls catalysts, while vinylene group of 4VCHE did not participate in the reaction, but it affected the polymerization rate of 4VCHE. The effects of aluminum alkyl and type of TiCl3 on the polymerization were examined. The overall activation energy for the polymerization was estimated to be 41.9kJ/mol. Monomer-isomerization copolymerization of 4VCHE and trans-2-butene occurred with the TiCl3-(i-C4H9)3Al catalyst to give copolymers consisting of 4VCHE and 1-butene units.
