A novel supported catalyst component useful for .alpha.-olefin polymerization and a method of polymerizing an .alpha.-olefin using the same. The catalyst component is characterized by being prepared by contacting a complex represented by general formula (I) wherein R1 and R2 are the same or different and each represents a C1-6 linear or branched alkyl, a C1-3 haloalkyl, or optionally substituted phenyl; and X represents a halogeno with a magnesium compound.

L'invention porte sur un nouveau catalyseur sur support servant à la polymérisation des alpha -oléfines et un procédé associé de polymérisation des alpha -oléfines. Ledit catalyseur se prépare en mettant en contact un complexe de formule (I) dans laquelle: R<1> et R<2> sont identiques ou différents et représentent chacun un alkyle C1-6 linéaire ou ramifié, un haloalkyle C1-3, ou un phényle facultativement substitué; et X représente halogéno, avec un composé de magnésium.
