Title (EN) MIXED PHOSPHINIMINE CATALYST
(FR) CATALYSEUR DE PHOSPHINIMINE MIXTE
Abstract: front page image
(EN)A supported catalyst for the polymerization of olefins, especially ethylene, has at least two catalyst components having different propagation and/or termination constants. Each catalyst component must have at least one phosphinimine ligand. The polymer produced according to this invention has a broad molecular weight distribution. Catalysts according to this invention have a very surprising and desirable hydrogen response.
(FR)L'invention concerne un catalyseur sur support utile dans la polymérisation d'oléfines, spécialement d'éthylène, qui comporte au moins deux constituants de catalyseur présentant des constantes de propagation et/ou de terminaison différentes. Chaque constituant de catalyseur doit contenir au moins un ligand de phosphinimine. Le polymère produit selon l'invention présente une large distribution des masses moléculaires. Les catalyseurs de l'invention présentent une réaction à l'hydrogène très surprenante et souhaitable.
