Title (EN) ETHYLENE ALPHA-OLEFIN COPOLYMERS WITH MULTIMODAL COMONOMER DISTRIBUTIONS AND PROCESSES FOR OBTAINING THE SAME
(FR) COPOLYMÈRES D'ÉTHYLÈNE ALPHA-OLÉFINE AYANT DES DISTRIBUTIONS DE COMONOMÈRES MULTIMODALES ET LEURS PROCÉDÉS D'OBTENTION
Abstract:
(EN) A polymer composition may include a plurality of ethylene-based polymers forming a multimodal composition distribution, each having a distinct crystallization peak in a CEF curve. A process of making a polymer composition may include melt blending a plurality of polyethylenes with different microstructural characteristics in the molten state. Another process of making a polymer composition may include polymerizing ethylene and an optional alpha olefin in combination with a plurality of metallocene catalysts in a polymerization reactor to form a plurality of ethylene based polymers. Yet another process of making a polymer composition may include polymerizing ethylene and an optional alpha olefin in combination with a multimetal catalyst in a polymerization process to form a plurality of ethylene based polymers.
(FR) Une composition polymère peut comprendre une pluralité de polymères à base d'éthylène formant une distribution de composition multimodale, présentant chacun un pic de cristallisation distinct dans une courbe CEF. Un procédé de fabrication d'une composition polymère peut comprendre le mélange par fusion d'une pluralité de polyéthylènes présentant différentes caractéristiques microstructurales à l'état fondu. Un autre procédé de fabrication d'une composition polymère peut comprendre la polymérisation d'éthylène et d'une alpha-oléfine facultative en combinaison avec une pluralité de catalyseurs métallocènes dans un réacteur de polymérisation pour former une pluralité de polymères à base d'éthylène. Encore un autre procédé de fabrication d'une composition polymère peut comprendre la polymérisation d'éthylène et d'une alpha-oléfine facultative en combinaison avec un catalyseur multimétallique dans un processus de polymérisation pour former une pluralité de polymères à base d'éthylène.
