Abstract: front page image
(EN)The present invention relates to novel cocatalysts comprising (a) a Lewis base and a hydroxy compound and (b) a Lewis acid. Typical Lewis bases are amines and the hydroxy compound is suitably a phenol. The Lewis acid may be tris(pentafluorophenyl) borane. The cocatalysts are typically used in the presence of transition metal compounds for the polymerisation of olefins particularly when supported for use in the gas phase.
(FR)L'invention concerne de nouveaux cocatalyseurs comprenant : (a) une base de Lewis et un composé hydroxy et (b) un acide de Lewis. Les bases de Lewis typiques sont des amines et le composé hydroxy approprié est un phénol. L'acide de Lewis peut être du tris(pentafluorophényl) borane. Typiquement, les cocatalyseurs sont utilisés en présence de composés d'un métal de transition pour la polymérisation d'oléfines, notamment lorsqu'ils sont supportés pour être utilisés dans la phase gazeuse.
