Abstract

1489410 Ziegler polymerization catalyst MONSANTO CO 31 Dec 1974 [2 Jan 1974 (2) 5 June 1974] 56153/74 Heading C3P Olefin, particularly ethylene, polymerization catalysts comprise (a) a vanadium compound or (b) a mixture obtained by reacting a vanadium compound and a hydrocarbyl aluminium hydrocarbyloxide followed by addition of a trialkylaluminium, in either case supported on (c) a silica support obtained by drying silica gel and depositing thereon a trihydrocarbylaluminium or a hydrocarbylaluminium halide or hydrocarbyloxide. Examples refer to the homopolymerization of ethylene or copolymerization thereof with propylene in hexane or in a fluidized bed, in some cases using hydrogen, CHCl 3 or CFCl 3 as modifiers, and in the presence of (a) VOCl 3 or (b) or Et 3 Al 2 (OEt) 3 reaction product followed by Et 3 Al, supported on (c) dried silica gel which has been reacted with Et 3 Al, EtAl(OEt) 2 or additional Et 3 Al also being present during the polymerization.
