Title (EN) PROCESS FOR PRODUCING OLEFIN POLYMER
(FR) PROCEDE DE PRODUCTION D"UN POLYMERE D"OLEFINE
Abstract: front page image
(EN)A process for producing a polyolefin having high polymerization activity and high molecular weight or a polyolefin, particularly polyethylene, having a wide molecular weight distribution adapted for extrusion or blow-molding, comprising the step of polymerizing olefin such as ethylene by the use of a catalyst system which comprises organic aluminum compound and solid catalyst component obtained by mixing or reacting organic oxygenated compounds or halides of metals such as (a) vanadium and (b) hafnium, or solid catalyst component obtained by mixing and reacting organic oxygenated compounds or halides of metals such as (A) vanadium, (B) hafnium and (C) titanium with (D) organic aluminum compound.
(FR)Un procede de production d"une polyolefine ayant une grande activite de polymerisation et un poids moleculaire eleve ou une polyolefine, en particulier du polyethylene, ayant un poids moleculaire largement distribue et se pretant a l"extrusion ou le moulage par soufflage, consiste a polymeriser une olefine telle que de l"ethylene en utilisant un systeme catalyseur comprenant un compose organique d"aluminium et un catalyseur solide obtenu par melange ou par reaction de composes oxygenes organiques ou d"halogenures de metaux tels que (a) du vanadium (b) de l"hafnium, ou un catalyseur solide obtenu par melange et reaction de composes oxygenes organiques ou d"halogenures de metaux tels que (A) du vanadium, (B) de l"hafnium et (c) du titane avec (D) un compose d"aluminium organique.
