Title
(EN) COMPOSITIONS EXHIBITING HIGH ESCR AND COMPRISING MONOVINYLIDENE AROMATIC POLYMER AND ETHYLENE/ALPHA-OLEFIN COPOLYMER
(FR) COMPOSITIONS PRESENTANT UNE RESISTANCE ELEVEE A LA FISSURATION SOUS CONTRAINTE DANS UN ENVIRONNEMENT DONNE ET CONTENANT UN POLYMERE AROMATIQUE MONOVINYLIDENE ET UN COPOLYMERE ETHYLENE/ALPHA-OLEFINE
Abstract
(EN)
Compositions comprising (a) a monovinylidene aromatic polymer, e.g., HIPS, and (b) an ethylene/alpha-olefin (EAO) copolymer, e.g., an ethylene-propylene copolymer, that satisfies the mathematical relationship: y ≤ 20 + 2.35x in which y is the ethylene content in mole percent (mol%) of the EAO copolymer and x is the Brookfield viscosity in centipoise (cP) at 10O°C of the EAO copolymer and the viscosity is at least 1 centipoise (cP), exhibit improved environmental stress crack resistance as compared to compositions containing monovinyiidene aromatic polymers but without such an EAO copolymer. The compositions are useful in the manufacture of articles, e.g., refrigerator liners and food packaging, which come in contact with the oils contained in various food stuffs.
(FR)
L'invention concerne des compositions contenant : (a) un polymère aromatique monovinylidène, par exemple HIPS, et (b) un copolymère éthylène/alpha-oléfine (EAO), par exemple un copolymère éthylène-propylène, satisfaisant à la relation mathématique : y ≤ 20 + 2,35x, dans laquelle y représente la teneur en éthylène en pourcentage molaire (%mol) du copolymère EAO et x représente la viscosité Brookfield en centipoises (cP) à 100°C du copolymère EAO, ladite viscosité étant d'au moins un 1 centipoise (cP). Les compositions selon l'invention présentent une résistance améliorée à la fissuration sous contrainte dans un environnement donné par rapport à des compositions contenant des polymères aromatiques monovinylidène sans ce type de copolymère EAO. Ces compositions sont utiles dans la fabrication d'articles, par exemple des cuves internes de réfrigérateurs et des emballages alimentaires, venant en contact avec les huiles contenues dans divers produits alimentaires.
