Abstract[English]
A catalyst activity aid for improving the productivity of a catalyst in polymerization processes is disclosed. The catalyst activity aid comprises a mixture of (a) a polysulfone copolymer; (b) a polyquaternary ammonium salt; and (c) a carrier fluid. The catalyst activity aid is particularly suitable for improving the catalyst productivity of metallocene catalysts used in polymerization processes such as those for the production of ethylene-based and propylene-based polymers.[French]
L'invention concerne un auxiliaire de catalyseur permettant d'améliorer la productivité d'un catalyseur dans des procédés de polymérisation. L'auxiliaire de catalyseur comprend un mélange de (a) un copolymère de polysulfone; (b) un sel d'ammonium polyquaternaire; et (c) un fluide porteur. L'auxiliaire de catalyseur est particulièrement approprié pour améliorer la productivité de catalyseurs métallocènes utilisés dans des procédés de polymérisation tels que ceux destinés à la production de polymères à base d'éthylène et à base de propylène.
