Patent

CA 2729585

Provided are ethylene copolymers and a process for preparing the same. More specifically, provided are ethylene copolymers exhibiting excellent processibility and physical properties due to its multimodal molecular weight distribution index, through a multi-stage process by using reactors connected in series or in parallel in the presence of catalyst composition containing transition metal catalyst, and a process for preparing the same.

La présente invention concerne des copolymères d'éthylène et un procédé pour préparer ceux-ci. Plus spécifiquement, la présente invention concerne des copolymères d'éthylène présentant une excellente aptitude au traitement et d'excellentes propriétés physiques en raison de leur indice de distribution de poids moléculaire multimode, obtenus selon une procédure multi-étape en utilisant des réacteurs raccordés en série ou en parallèle en présence d'une composition de catalyseur contenant un catalyseur à métal de transition, et un procédé pour préparer ceux-ci.
