Title (EN) ELASTOMERIC COMPOSITIONS
(FR) COMPOSITIONS ÉLASTOMÈRES
Abstract:
(EN) This invention relates a composition comprising: (i) at least one low molecular weight polyolefm; (ii) a block copolymer obtainable by selectively hydrogenating a block copolymer having terminal polymeric blocks of a vinyl aromatic monomer and a mid-block prepared originally with an olefin and subsequently hydrogenated; and (iii) polypropylene; (iv) with the proviso that when (i) is a PAO having a molecular weight of between about 400 and 1000 g/mole, either: (a) (iii) is a homopolymer characterized by an MFR greater than 2 g/10 min, (b) (iii) is a copolymer; or (c) (iii) is a polymer or copolymer made by a metallocene catalyst; or (d) the composition does not contain calcium carbonate.
(FR) La présente invention concerne une composition comprenant : (i) au moins une polyoléfine de faible poids moléculaire ; (ii) un copolymère bloc qu’il est possible d’obtenir par l’hydrogénation sélective d’un copolymère bloc ayant des blocs polymères terminaux d’un monomère aromatique vinylique et un bloc médian préparé à l’origine avec une oléfine et subséquemment hydrogéné ; et (iii) du polypropylène ; (iv) avec la provision que lorsque (i) est un PAO ayant un poids moléculaire compris entre environ 400 g/mole et 1 000 g/mole, (a) (iii) est un homopolymère caractérisé par un MFR supérieur à 2 g/10 min ; (b) (iii) est un copolymère ; (c) (iii) est un polymère ou un copolymère fait par un catalyseur métallocène ; ou (d) la composition ne contient pas de carbonate de calcium.
