A supported catalyst component comprising (a) a support material, an organometal compound, and (b) an activator compound comprising b.1) a cation which is capable of reacting with a transition metal compound to form a catalytically active transition metal complex, and b.2) a compatible anion having up to 100 nonhydrogen atoms and containing at least one substituent comprising an active hydrogen moiety; a supported catalyst comprising the supported catalyst component and a transition metal compound; process for making the same; an addition polymerization process using the supported catalyst; complex compounds, and a method for preparing the same.

Ce constituant de catalyseur sur support comprend: a) un matériau support, un composé organométallique et b) un composé activateur comprenant: b. 1) un cation capable de réagir en association avec un composé métallique de transition à activité catalytique pour donner un complexe métallifère de transition d'activité catalytique, et b. 2) un anion compatible contenant jusqu'à 100 atomes autres que d'hydrogène et au moins un substituant comprenant une partie active d'hydrogène. On décrit également les éléments suivants: un catalyseur sur support comprenant le constituant de catalyseur sur support et un composé métallique de transition, ainsi que le procédé de préparation dudit catalyseur, un procédé de polymérisation par addition avec utilisation du catalyseur sur support et, enfin, des complexes accompagnés d'une méthode de préparation.
