Abstract
PURPOSE:The copolymerization of propylene and an alpha-olefin is conducted in the presence of a catalyst of titanium trichloride and an organoaluminum compound under specific conditions in accordance with specified procedures. CONSTITUTION:In the presence of a catalyst consisting a titamium trichloride composition further activated by reducing titanium tetrachloride with an organoaluminum conpound and an organoaluminum compound of the formula, R2AlX (R is hydrocarbyl, X is halogen) is at first polymerized 0.01-50 parts by wt, per 1 part of the titanium trichloride, of propylene, then a C4-10 alpha-olefin and propylene are fed and polymerized at a temperature T satisfying the equation, in which C is mole% of the alpha-olefin in the copolymer, thus producing a crystalline propylene- alpha-olefin copolymer containing 8-25 mol% of alpha-olefin unit.
