Abstract

Ethylenically unsaturated hydrocarbons, e.g. ethylene, propylene and butadiene are polymerized in the presence of a catalyst comprising the reaction product of (a) a compound of a transition metal from Group IVA, VA or VIA of the Periodic Table, (b) an aluminium halide, and (c) RxSiR14- x, where R=aryl, substituted aryl or alkyl, R1 represents alkyl, hydrogen, halogen or a group Si(R2)3, R2 being aryl and x = 1-4. Examples describe the preparation of solid polyethylene, ethylene/propylene copolymers and polybutadiene. Polymerization may be effected at -50 DEG C. to 150 DEG C., at 0-2000 atmospheres, with or without a solvent. Specifications 946,013 and 962,952 are referred to.ALSO:Ethylenically unsaturated hydrocarbons are polymerized in the presence of a catalyst comprising the reaction product of (a) a compound of a transition metal from Group IVa, Va or VIa of the Mendel<\>aeeff Perodic Table: Ti, Zr, Hf, Th, V, Nb, Ta, Pa, Cr, Mo, W and U. (b) an aluminium halide, and (c) RxSiR14-x where R=aryl, substituted aryl or alkyl, R1 represents alkyl, hydrogen, halogen or a group Si(R2)3, R2 being aryl and x=1-4. Specified transition metal compounds are TiCl3, TiCl4, CrO2Cl2, VCl4, VCl3 and vanadium and titanium di-isopropylsalicylate. The polymerization catalysts may be prepared in the presence of pumice, Al2O3 or SiO2. Specifications 946,013 and 962,952 are referred to.
