Abstract

Catalyst residues are removed from polyolefins produced by the Ziegler low-pressure process, by contacting the polymerization product with a solution of an aluminium halide, such as the chloride, in an organic solvent prior to treatment with a selective solvent such as methyl-, ethyl- or benzyl-alcohol or cyclohexanol. The organic solvents specified are diethyl-, dichlorodiethyl- and dicyanodiethylethers. The description refers to the polymerization of ethylene, propylene or butylene with a catalyst comprising a Group 4a, 5a, 6a or 7a compound plus a hydride or metal-alkyl or -aryl of a Group 2 or 3 metal. In examples the polymerization process components comprise octane, xylene, petroleum ether, titanium tetrachloride, and aluminium-triethyl, -triisobutyl, -diisobutyl chloride, or -diethyl chloride. Specifications 713,081; 742,642, 773,536, [both in Group IV (b)], 799,392 and German Specification 878,560 are referred to.
