Abstract

Block copolymers of ethylene with higher alpha-olefins are made by a process in which a first monomer is polymerized in a polymerization zone and is then transferred to another polymerization zone where it is contacted with a second monomer to add a further polymer block to it. The polymerization may be carried out in an apparatus consisting of two polymerization reactors through which the polymerized material is continuously circulated, polymerization of ethylene occuring in one reactor and polymerization of a different olefin in the other. The examples describe making ethylene-propylene block copolymers with the aid of a titanium trichloride-aluminium diethyl chloride catalyst, polymerization being carried out in the gaseous phase.
