| titleOfInvention | Copolymerisation of alpha-olefins |
| abstract | A polymerization catalyst comprises the product obtained by mixing in an inert solvent an aluminium alkyl dihalide, vanadium oxytrichloride or tribromide, and an organic sulphur compound containing at least one phenyl group selected from sulphones, sulphides, disulphides, sulphoxides and sulphonamides. The mol ratio of the aluminium compound to the vanadium compound is from 1:1 to 10:1 and the mol ratio of the aluminium compound to the organic sulphur compound is from 12:1 to 2:1. The organic sulphur compound may be phenyl or benzyl sulphone, phenyl sulphide, phenyl disulphide, benzyl disulphide, tolyl sulphone, tolyl sulphide, phenyl sulphoxide, tolyl sulphoxide, or N,N-dimethyl p-toluene sulphonamide. The inert diluent may be a hydrocarbon or halogenated hydrocarbon. The catalyst is used for making copolymers of ethylene and/or propylene or butene, and which optionally contain a very small amount of a diene, e.g. cyclopentadiene. The copolymers are recovered by conventional techniques, e.g. addition of an alcohol, and may be vulcanized and cross-linked by known methods. Specification 954,133 is referred to. |
