Title (EN) PROPYLENE POLYMERIZATION CATALYST AND METHOD
(FR) PROCEDE ET CATALYSEUR DE POLYMERISATION DU PROPYLENE
Abstract:
(EN) A catalyst component useful in propylene polymerization in combination with a dialkyl aluminum halide cocatalyst comprises the product of reaction of TiCl3 which is substantially free of extraneous halide with a selected electron donor compound which is dissolved in a liquid hydrocarbon solvent in which the TiCl3 is dispersed. The electron donor compound is selected from certain organic acid esters, hindered phenolic compounds and silyl esters. The catalyst of the invention provides increased activity, molecular weight control, increased isotacticity of propylene polymer products and prevents catalyst feed line pluggage, among other advantages.
(FR) Un composant de catalyse utile dans la polymérisation du propylène en combinaison avec un catalyseur associé à base d'halogénure d'aluminium dialkyle comprend le produit de réaction de TiCl3 qui est sensiblement exempt d'halogènure étranger avec un composé sélectionné donneur d'électrons qui est dissous dans un solvant d'hydrocarbure liquide dans lequel TiCl3 est dispersé. Le composé donneur d'électrons est sélectionné parmi certains esters d'acide organique, des composés phénoliques empêchés et des esters de silyle. Le catalyseur de l'invention présente une activité accrue, une meilleure régulation du poids moléculaire, une isotacticité acrue des produits de polymère de propylène et empêche l'occlusion de la ligne d'alimentation du catalyseur, et présente d'autres avantages.
