Abstract
An ethylene polymerization catalyst comprises a mixture of a titanium/zinc alloy and an alkyl halide of formula RX or an alkylene halide of formula X(CH2)nX where R is an alkyl or cycloalkyl group, X is chlorine, bromine or iodine and n is an interger not less than 3. The atomic ratio of the halogen to the zinc is preferably between 0.5 and 5 and the alloy and halide are preferably mixed and heated together (preferred 50-100 DEG C.) and then milled-preferably ball-milled in the presence of an inert hydrocarbon dispersing medium.ALSO:Ethylene is polymerized using as catlyst a mixture of a titanium/zinc alloy and an alkyl halide or an alkylene halide. The alkyl halide has the formula RX and the alkylene halide X(CH2)nX where R is an alkyl or cyclo alkyl group, X is chlorine, bromine or iodine and n is an integer not less than 3. The polymerization may be carried out at 50 DEG to 150 DEG C. in an inert dispersing medium.
