Abstract

Procedure for polymerizing an alpha-olefin under conditions characteristic of Ziegler polymerization, characterized in that the reaction product of (A) a compound of a transition metal (MT), (B) (1) an organomagnesium compound is used as a catalyst or (2) a complex of an organomagnesium compound and an organometallic compound, in an amount sufficient to solubilize the organomagnesium compound in hydrocarbon, and (C) a non-metal halide corresponding to the formula R'X, where X is halogen and R'is hydrogen or an organic group at least as active as sec-butyl; the atomic ratio of Mg: MT is between 20: 1 and 2000: 1, the atomic ratio of X: MT is between 40: 1 and 2000: 1, and the atomic ratio of Mg: X is between 0.1 : 1 and 1: 1.
