Abstract

A polymerization catalyst is prepared by treating a Group IVa-VIIa or VIII transition metal compound (preferably a halide, e.g. chloride of preferably Group IVa, Va, or Mo or W, particularly of Ti or V, especially TiCl4, VCl4 or TlCl3 and including AlTi3Cl12 made by the method of Specification 877,050 with a compound of formula R R1R2Al(CH2)AlR3R4 wherein the R groups, which may be identical or different are alkyl, cycloalkyl, aryl or aralkyl and n is an integer. It is preferred that:-(a) the Al compound is prepared by reacting an alpha omega dialkali metal derivative of a linear aliphatic hydrocarbon with an Al dihydrocarbon halide; (b) the R groups are alkyl, particularly of up to 4 carbon atoms each; (c) n is 3-6; (d) the mole ratio of the Al compound to transition metal compound is 0,1-1:1; (d) the catalyst is prepared in the presence of a hydrocarbon liquid, e.g. a petroleum ether whose boiling point is over 120 DEG C., said liquid being preferably free from sulphur-containing impurities. In examples, (Et2Al)2(CH2)5 and (Et2Al)2(CH2)4 are used as the aluminium compounds.ALSO:Ethylene, vinyl hydrocarbons (including propylene, styrene, butadiene and isoprene) and vinyl chloride are polymerized by contact with a polymerization catalyst prepared by treating a Group IVa-VIIa and VIII transition metal compound with R1R2Al(CH2)nAlR3R4 (see Group III). The following transition compounds are preferred for polymerizing the respective monomers:- (a) ethylene -TiCl4; (b) propylene, giving an isotactic polymer-aTiCl3, including the AlTi3Cl12 of Specification 877,050; (c) styrene, giving an isotactic polymer-VCl4; (d) butadiene-TiCl3 for a rubbery polymer, VCl4 for a crystalline polymer; (e) isoprene -TiCl4 for a rubbery polymer, VCl4 for a crystalline polymer.ALSO:a : o -bis(diethylaluminium)butane and -pentane etherates are obtained by treating powdered Li with 1 : 4-dibromobutane or 1 : 5-dibromopentane in diethyl ether at about -20 DEG C., adding the dilithium compound obtained to Et2AlBr, removing the LiBr formed and evaporating off the ether under reduced pressure. Specification 877,050 is referred to.
