Title (EN) PROPYLENE IMPACT COPOLYMER AND METHOD
(FR) COPOLYMÈRES-CHOCS À BASE DE PROPYLÈNE ET PROCÉDÉ DE FABRICATION ASSOCIÉ
Abstract:
(EN) Disclosed are propylene impact copolymer compositions, articles thereof, and processes for producing same. Polymerization with an improved catalyst composition provides a propylene impact copolymer with high melt flow and low volatiles content.
(FR) La présente invention concerne des compositions de copolymères-chocs à base de propylène, des articles fabriqués à partir de celles-ci, et leur procédé de fabrication. Une polymérisation avec une composition catalytique améliorée permet d'obtenir des copolymères-chocs à base de propylène présentant un écoulement à l'état fondu élevé et une faible teneur en composants volatils.
