Abstract

Propylene may be polymerized in the presence of a catalyst prepared by a process which comprises grinding titanium trichloride with lithium chloride under inert conditions and mixing the product with an aluminium alkyl. Grinding may be effected with rod, pebble, ball or jet mills; and grinding and polymerization may be effected in the presence of a solvent or diluent, e.g. pentane, hexane, cyclohexane, heptane, octane, isooctane, benzene, toluene or xylene. The aluminium alkyl may be aluminium triethyl or aluminium triisobutyl, or a dialkyl or monoalkyl aluminium chloride. The polymers may be purified by refluxing with a hydrogen chlorideisopropanol-acetyl acetone mixture. In Example I a catalyst of the invention is compared with one in which the lithium chloride is replaced by potassium chloride.
