Abstract

Copolymers of ethylene and an alpha-olefin which contain 4 to 20% by weight of the alpha-olefin are made by copolymerizing, at a temperature between 110 DEG and 140 DEG C., a mixture of ethylene and alpha-olefin in a ratio of from 0.03 to 0.3 moles of alpha-olefin per mole of ethylene, in the presence of a catalyst consisting essentially of a trialkyl aluminium compound, and purple TiCl3, and an inert non-polar solvent for the monomers such as a hydrocarbon, or halogenated hydrocarbon. The alpha-olefin may be propylene, a butene, or pentene. The copolymers are recovered by conventional techniques. Specification 851,002 is referred to.
