Abstract

Olefinic hydrocarbons are polymerised in the presence of a catalyst formed from a compound of a metal of sub-Group IV(A), V(A), VI(A) of the Periodic Table and an aluminium trialkyl, and a halogenated hydrocarbon. The hydrocarbon polymerised may be ethylene and/or propylene. Halogenated hydrocarbons mentioned are methyl chloride, dichloromethane, carbon tetrachloride, methyl bromide, dibromomethane, ethyl chloride, ethyl bromide, sym dichloroethane, n-propyl chloride, isopropyl chloride, monochlorobenzene, o-dichlorobenzene, difluorodichloromethane, trifluoromonobromomethane, trifluoromonoiodomethane, sym difluoro-dichlorethane, sym tetrafluoro-dichlorethane, sym tetrachlorodifluorethane and mixtures. The preferred catalyst is titanium tri- or tetrachloride with aluminium triethyl. The product may be a liquid. Specifications 799,392, 799,823 and 801,031 are referred to.
