Abstract

PURPOSE: To obtain the titled composition in the form of tack-free powder by vapor-phase polymerization, by polymerizing, in a vapor phase, propylene and a specified proportion of ethylene or an α-olefin with the aid of a catalyst system containing a titanium trichloride composition having a specified particle diameter.
CONSTITUTION: In producing a random copolymer by vapor-phase copolymerization of propylene and a comonomer selected from the group consisting of ethylene and an α-olefin with the aid of a catalyst system containing a titanium trichloride composition and an organoaluminum compound; the titanium trichloride composition has an average particle diameter of 10W100μ, and the copolymerization is carried out so that the formed random copolymer contains said comonomer in an amount of (a) 1.5W45wt% in case of polymerization of ethylen alone, (b) 10/(n-2)W98/(n-2)wt% α-olefin, (where n is the number of carbon atoms of the α-olefin) in case of copolymerization of α-olefin and (c) 0.5W16wt% ethylene and 6/(n-2)W68/(n-2)wt% α-olefin in case of copolymerization of ethylene with an α-olefin.
