Title (EN) HIGH MELT FLOW PROPYLENE IMPACT COPOLYMER AND METHOD
(FR) COPOLYMÈRE CHOC DU PROPYLÈNE À INDICE DE FUSION ÉLEVÉ ET PROCÉDÉ CORRESPONDANT
Abstract:
(EN) The present disclosure provides a polymerization process for the production of a high melt flow propylene impact copolymer. The process includes contacting an active propylene-based polymer having a melt flow rate greater than about 100 g/10 min with one or more olefins in a polymerization reactor to form the propylene impact copolymer with a melt flow rate greater than about 60 g/10 min. The production of the high melt flow propylene impact copolymer may occur in one or more polymerization reactors, utilizing standard hydrogen concentration, and no visbreaking.
(FR) La présente invention porte sur un procédé de polymérisation pour la production d'un copolymère choc du propylène à indice de fusion élevé. Le procédé comprend la mise en contact d'un polymère à base de propylène, actif, ayant un indice de fusion supérieur à environ 100 g/10 min avec une ou plusieurs oléfines dans un réacteur de polymérisation pour former le copolymère choc à base de propylène avec un indice de fusion supérieur à environ 60 g/10 min. La production du copolymère choc du propylène à indice de fusion élevé peut se présenter dans un ou plusieurs réacteurs de polymérisation, utilisant une concentration en hydrogène standard et sans viscoréduction.
