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, and (3) an organic solvent. In the catalyst system the proportion of (2) to (1) is 0.5 to 3.0:1. Polypropylene made by this process may have a heptane insolubility of 85 to 97%, an inherent viscosity of 7 to 13, and an approximate molecular weight of 1,000,000 to 3,000,000. 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 e.g. methanol and HCl. The polymerization is preferably effected in a continuous manner. The Grignard compound may be methyl magnesium bromide or ethyl magnesium chloride. The ether portion of the complex may be diethyl, ethyl propyl, dibutyl, or diisopropyl ethers. Specification 944,929 also is referred to.
