Abstract
Propylene is polymerized in the presence of a catalyst formed by mixing an aluminium trialkyl with a lithium alkyl in a molar ratio of between 1 : 1 and 1 : 3 respectively, and then reacting the mixture with a titanium tetrahalide in a proportion of aluminium to titanium atoms between 0.75 : 1 and 2.0 : 1. The polymerization is preferably effected with the catalyst dispersed in an inert hydrocarbon solvent, e.g. petroleum ether or methylcyclohexane, at from 0 DEG to 150 DEG C. and from 50 to 500 p.s.i. pressure, or the propylene may be passed over the surface of the stirred medium. The lithium alkyl may be lithium ethyl, propyl or n-butyl and the aluminium trialkyl may be aluminium trimethyl, triethyl, tripropyl, tri-n-butyl or tri-isobutyl. The titanium tetrahalide may be the chloride or bromide. The crystalline polypropylene product may be purified by washing with methanol and/or dilute methanolic hydrochloric acid. The Provisional Specifications specify also the polymerization of butene-1. Specification 785,314 is referred to.
