Abstract

Alpha olefins are polymerized alone or in admixture at comparatively low pressures to produce polymers employing a two-component catalyst wherein one component is an organozinc or organomagnesium compound, e.g. zinc diethyl, magnesium diphenyl, propyl magnesium chloride, etc. The other component is a salt, oxide or hydroxide of a metal of Group IV-B, V-B or VI-B of the Periodic System, including thorium and uranium.
