Abstract
A catalyst and a method of polymerizing a monomer comprising ethylene in which the catalyst is prepared by dispersing on a dry finely divided, difficultly reducible inorganic oxide support such as silica a reaction product prepared by reacting pinacol with a chromium compound in which the reaction product is fixed to the support by heating at an elevated temperature in a non-oxidizing atmosphere.
