Abstract
L’invention concerne un système catalytique supporté sur un support inorganique poreux, dans lequel le système catalytique est à base au moins d’un métallocène de terre rare et d’un organomagnésien, ainsi que son procédé de préparation par imprégnation. Son utilisation dans la polymérisation d’éthylène et la copolymérisation d’éthylène avec des α-oléfines en phase gazeuse permet la synthèse de polyoléfines semi-cristallines de hautes masses molaires sous la forme de particules polymères de morphologie bien contrôlée, notamment la synthèse de polyéthylènes d’ultra hautes masses molaires, UHMWPE.
