Abstract of the Disclosure A solution polymerization process for the prepara- tion of high molecular weight polymers of .alpha.-olefins selected from the group consisting of homopolymers of ethylene and copolymers of ethylene and C3 - C12 .alpha.-olefins is disclosed. The process comprises feeding monomer(s), coordination cata- lyst and inert hydrocarbon solvent to a reactor, polymerizing the monomer(s) at a temperature of up to 320°C and a pressure of less than 25 MPa, and deactivating the catalyst in the solution so obtained. The catalyst is deactivated by sequen- tially admixing therewith a minor amount of water followed by a solution of a salt of an alkaline earth meta or zinc and an aliphatic monocarboxylic acid dissolved in hydrocar- bon solvent. The hydrocarbon solvent and other volatile matter are then separated from the resultant solution and a composition comprising said high molecular weight polymer is recovered. The amount of water added is not more than 2.5 moles of water per mole of halogen plus alkyl radicals in the coordination catalyst. In an embodiment the water has a water-soluble metal chelating agent dissolved therein.
