A catalyst composition for producing linear low density polyethylene with relatively narrower molecular weight distributions is described. The catalyst is formed by treating silica having reactive OH groups with a dialkylmagnesium in a solvent for said dialkylmagnesium; then adding to said magnesium- containing support a mixture of R''OH and SiCl4 to form an intermediate which is subsequently treated with a transition metal to form a transition metal- containing intermediate, the catalyst precursor. The catalyst precursor is activated with a trialkylaluminum compound.

On décrit une composition de catalyseur pour la production de polyéthylène basse densité avec une distribution relativement plus étroite des poids moléculaires. On obtient le catalyseur en traitant de la silice ayant des groupes OH réactifs avec un dialkylmagnésium dans un solvant pour ledit dialkylmagnésium; ensuite en ajoutant audit support contenant du magnésium un mélange de R''OH et de SiCl¿4?, pour former un intermédiaire qui est ensuite traité avec un métal de transition pour former un intermédiaire contenant un métal de transition, qui constitue le précurseur du catalyseur. Le précurseur du catalyseur est activé avec un composé trialkylaluminium.
