Polymerization catalyst, production and use (P-1010)

Claim 1

A process for the polymerization of ethylene and alpha-olefins having from 1 to 20 carbon atoms or mixtures of ethylene, alpha-olefins and diolefins, which process comprises polymerizing in the presence of a catalyst system comprising (a) an organo aluminum compound of the formula AIR" n X" 3-n wherein R" is hydrogen or a hydrocarbyl group having from 1 to 20 carbon atoms, X is halogen and n is a number from 1 to 3, and (b) a transition metal containing catalyst component comprising the solid reaction product obtained by treating an inert solid support material in an inert solvent sequentially with (A) an organometallic compound of a Group IIa, IIb or IIIa metal wherein all the metal valencies are satisfied with a hydrocarbon group, (B) an oxygen containing compound selected from ketones, aldehydes, alcohols, siloxanes or mixtures thereof, (C) optionally one or more halogen containing compounds selected from chlorosilanes and/or Cl 2 , Br 2 or interhalogens, (D) at least one transition metal compound of a Group IVb, Vb, VIb or VIII metal, (E) optionally Cl 2 , Br 2 or an interhalogen, and (F) treating the transition metal containing component with an organometallic compound of a Group IIa, IIb or IIIa metal, with the proviso that if a chlorosilane is not employed in step (C), then Cl 2 , Br 2 or an interhalogen is employed in at least one of steps (C) or (E), if a chlorosilane is employed in step (C), then Cl 2 , Br 2 or an interhalogen is additionally employed in step (C) and/or step (E), and with the further proviso that the inert solid support material can also be treated with (i) the (A) organometallic compound and the (B) oxygen containing compound simultaneously, (ii) the reaction product of the (A) organometallic compound and (B) oxygen containing compound or (iii) the (B) oxygen containing compound followed by treating with the (A) organometallic compound.
