CA 2261669

The present invention relates to a solid catalyst component for the polymerization of olefins CH2=CHR in which R is hydrogen or a hydrocarbyl radical with 1-12 carbon atoms, comprising a titanium compound, having at least a Ti-halogen bond and an electron donor compound supported on an Mg halide, in which said electron donor compound is selected from esters of malonic acids of formula (I), wherein R1 is a C5-C20 linear or branched alkyl, a C5-C20 cycloalkyl, a C7-C20 arylalkyl or alkylaryl group; R2 and R3, equal to or different from each other, are C1-C3 alkyl, cycloalkyl. Said catalyst components when used in the polymerization of olefins, and in particular of propylene, are capable to give high yields and polymers having high insolubility in xylene.

La présente invention concerne un catalyseur solide pour la polymérisation d'oléfines CH¿2?=CHR, dans lesquelles R représente hydrogène ou un radical hydrocarbyle avec 1-12 atomes de carbones, comprenant un composé de titane, ayant au moins une liaison de Ti-halogène et un composé donneur d'électrons supporté sur une halogénure de Mg, où le donneur d'électrons est sélectionné parmi des esters d'acides maloniques présentant la formule (I). Dans cette dernière, R¿1? est un groupe alkyle C¿5?-C¿20? linéaire ou ramifié, cycloalkyle C¿5?-C¿20?, arylalkyle C¿7?-C¿20?, ou alkylaryl; R¿2? et R¿3? sont égaux ou différents l'un de l'autre et représentent alkyle C¿1?-C¿3?, cycloalkyle. Lors de leur utilisation dans la polymérisation des oléfines, ces catalyseurs assurent un grand rendement et peuvent donner des polymères insolubles dans le xylène.
