Abstract
Olefin polymers are made by polymerizing one or more olefins in the presence of a catalyst system consisting of the reaction product of an organometallic aluminium compound with a compound of a transition metal in a valency state below normal, and regulating the molecular weight of the product with an olefinically unsaturated aliphatic halide e.g. vinyl chloride or bromide or allyl or methallyl halides. The halide which is present in small amounts is generally introduced into the polymerization zone in admixture with the olefin. The aluminium compound may be the triethyl, triisobutyl, tri-n-propyl, trihexyl, triphenyl, tricyclohexyl, diethyl monochloride, monobromide, or monohydride. Transition metal compounds mentioned are titanium trichloride, vanadium trichloride, and vanadyl di- and trichlorides. The olefins may be ethylene, propylene, butene-1, and a mixture of ethylene and propylene. The polymerization may be effected in bulk or in the presence of a hydrocarbon diluent.
