Abstract
Polypropylene is made by polymerizing propylene in the presence of a catalyst system comprising (1) a composition containing titanium, chlorine and aluminium of the type described in Specification 895,418, and which is preferably made by heating a mixture of aluminium metal, titanium tetrachloride, and optionally an organic solvent at a temperature between 80 and 220 DEG C., (2) a Grignard-ether complex of the formula RMgX. nR12O, where R is a lower alkyl, X is chlorine, bromine, or iodine, n is 0.1 to 1.3 and R12O is an ether, (3) molecular hydrogen, and (4) an organic solvent. In the catalyst system the proportion of (2) to (1) is 0.5 to 3.0:1. The polypropylene may have an original crystallinity of at least 73.6% and a heptane extractable fraction crystallinity of at least 60% as measured by X-ray diffraction patterns, and an approximate molecular weight of 400,000 to 1,100,000. The organic solvent is usually a hydrocarbon, or a hydrocarbon mixture containing at least 10% of an aromatic hydrocarbon. The polymer is recovered and purified by conventional techniques. The polymerization is preferably effected in a continuous manner. The Grignard compound may be methyl magnesium bromide or ethyl magnesium chloride.
