Abstract
This invention relates to the polymerization of .alpha.-olefins and to catalysts and to cocatalysts for that purpose wherein the polymerization is carried out in the presence of a catalyst comprising an organometallic compound of a metal of Groups IA, IIA, IIB, IIIA, and IVA of the Periodic Table and a cocatalyst comprising a reaction product of a halogenated derivative of a transition metal of Groups IVB, VB, and VIB of the Periodic Table and a hydrous divalent metal salt of a carboxylic acid, the cocatalyst having a gram equivalent ratio of halogen/divalent metal plus transition metal greater than 0.5. The invention also comprises the method of making the cocatalysts.
