Abstract
Polyisoprene, and copolymers of isoprene with at least one other conjugated diolefin, is made by effecting the polymerization in the presence of a catalyst comprising a mixture of an organoaluminium compound containing no halogen, iodide, and a T1 tetrahalide wherein the organoaluminium compound ranges from 50 to 80 mol. per cent, the iodine from 5 to 40 mol. per cent, and the Ti halide from 10 to 45 mol. per cent of the mixture. The other diolefins may be butadiene-1,3, 2-isopropyl butadiene-1,3, 2,3-dimethyl butadiene, piperylene, or hexadiene. The organoaluminium compound may be a di- or tri-hydrocarbon aluminium compound. The polymerization may be effected in bulk or in an inert hydrocarbon diluent. The catalyst may be formed in situ or preformed. Exemplified catalysts are triisobutyl aluminium, iodine and TiCl4, in varying proportions. There are three examples of the copolymerization of isoprene and butadiene.
