Title (EN) MULTI-COMPONENT CATALYST COMPOSITION SUPPLY SYSTEM AND PROCESS FOR PRODUCING POLYMERS
(FR) SYSTÈME D'ALIMENTATION EN CATALYSEUR MULTICOMPOSANT ET PROCÉDÉ DE PRODUCTION DE POLYMÈRES
Abstract:
(EN) A polymerization catalyst supply system is provided. The polymerization catalyst supply system can be used to prepare polyolefin polymers with multimodal or broad molecular weight distribution, or to prepare polyolefins having broad compositional distribution. A process for preparing polyolefin polymers using the polymerization catalyst supply system is also provided.
(FR) L'invention concerne un système d'alimentation en catalyseur de polymérisation. Le système d'alimentation en catalyseur de polymérisation peut être utilisé pour préparer des polymères de polyoléfine ayant une distribution de poids moléculaire multimodale ou large, ou pour préparer des polyoléfines ayant une large distribution compositionnelle. L'invention concerne également un procédé de préparation de polymères de polyoléfine à l'aide du système d'alimentation en catalyseur de polymérisation.
