Title (EN) CATALYST COMPOSITION WITH MIXED SCA AND PROPYLENE POLYMERIZATION PROCESS
(FR) COMPOSITION DE CATALYSEUR RENFERMANT UN AGENT DE REGULATION DE SELECTIVITE ET PROCESSUS DE POLYMERISATION DE PROPYLENE
Abstract:
(EN) A catalyst composition for the polymerization of propylene comprising one or more Ziegler-Natta procatalyst compositions comprising one or more transition metal compounds and one or more esters of aromatic carboxylic acid internal electron donors; one or more aluminum containing cocatalysts; and a mixture of two or more different selectivity control agents, said SCA mixture comprising one or more esters of one or more aromatic monocarboxylic acids or substituted derivatives thereof and the reaction product or mixture formed by contacting one or more alkoxysilane compounds with an organoaluminum compound.
(FR) La présente invention se rapporte à une composition de catalyseur utilisée pour la polymérisation du propylène qui renferme au moins une composition de procatalyseur du type Ziegler-Natta comprenant au moins un composé de métaux de transition et au moins un ester d'acide carboxylique aromatique en tant que donneur d'électrons interne; au moins un cocatalyseur contenant de l'aluminium; et un mélange d'au moins deux agents de régulation de sélectivité (ARS) différents, ledit mélange des ARS comprenant un ou plusieurs esters d'au moins un acide monocarboxylique aromatique ou de dérivés substitués de ce(s) dernier(s) et le produit de réaction ou le mélange formé par la mise en contact d'au moins un composé alcoxysiloxane avec un composé organoaluminium.
