Title
(EN) BIMODAL POLY(ETHYLENE-CO-1-ALKENE) COPOLYMER
(FR) COPOLYMÈRE DE POLY(ÉTHYLÈNE-CO-1-ALCÈNE) BIMODAL
Abstract
(EN)
A bimodal poly(ethylene-co-1-alkene) copolymer comprising a higher molecular weight poly(ethylene-co-1-alkene) copolymer component and a lower molecular weight poly(ethylene-co-1-alkene) copolymer component. The copolymer is characterized by a unique combination of features comprising, or reflected in, its density; molecular weight distributions; component weight fraction amount; and viscoelastic properties; and at least one of environmental stress-cracking resistance and resin swell. Additional inventive embodiments include a method of making the copolymer, a formulation comprising the copolymer and at least one additive that is different than the copolymer, a method of making a manufactured article from the copolymer or formulation; the manufactured article made thereby, and use of the manufactured article.
(FR)
Un copolymère de poly(éthylène-co-1-alcène) bimodal comprenant un composant de copolymère de poly(éthylène-co-1-alcène) de poids moléculaire supérieur et un composant de copolymère de poly (éthylène-co-1-alcène) de poids moléculaire inférieur. Le copolymère est caractérisé par une combinaison unique de caractéristiques comprenant sa densité ou réfléchie dans sa densité; des distributions de poids moléculaire; une quantité de fraction de poids de composant; et des propriétés viscoélastiques; et au moins une caractéristique entre la résistance à la fissuration sous contrainte environnementale et le gonflement de la résine. D'autres modes de réalisation de l'invention comprennent un procédé de fabrication du copolymère, une formulation comprenant le copolymère et au moins un additif qui est différent du copolymère, un procédé de fabrication d'un article manufacturé à partir du copolymère ou de la formulation; l'article fabriqué ainsi fabriqué, et l'utilisation de l'article fabriqué.
