Abstract
A process for the polymerization or copolymerization of an olefinically unsaturated monomer which comprises contacting the monomer with a chromium metal catalyst composition which is the product obtained by adsorbing a chromium metal complex which contains allyl hydrocarbon radicals with an inert inorganic oxide support which has --OH groups on its surface and which is free from adsorbed water, said monomer being an olefinically unsaturated monomer other than a polar vinyl monomer.
