Title (EN) POLYMERIZATION CATALYST AND PROCESS
(FR) CATALYSEUR DE POLYMERISATION ET PROCEDE CORRESPONDANT
Abstract:
(EN) An olefin polymerization process is provided comprising contacting an olefin monomer with chromium oxide on a titanium containing silica support having less than about 3 weight percent titanium in combination with an organoboron promoter. Polymers thus produced are useful for blow molding applications.
(FR) Le procédé de polymérisation d'oléfine de l'invention consiste à prendre un monomère d'oléfine et à le mettre en contact avec un oxyde de chrome. En l'occurrence, on utilise un support silicique contenant du titane à raison d'environ 3% en masse au maximum, en association avec un promoteur organoboré. Les polymères ainsi produits sont particulièrement adaptés aux applications de moulage par soufflage.
