(FR) INTERPOLYMERES SEQUENCES D'ETHYLENE ET D'?LPHA-OLEFINES
Abstract
(EN)
Embodiments of the invention provide a class of ethylene/&agr;-olefÊn block interpolymers. The ethylene/&agr;-olefÊn interpolymers are characterized by an average block index, ABI, which is greater than zero and up to about 1.0 and a molecular weight distribution, Mw/Mn, greater than about 1.3. Preferably, the block index is from about 0.2 to about 1. In addition or alternatively, the block ethylene/&agr;-olefin interpolymer is characterized by having at least one fraction obtained by Temperature Rising Elution Fractionation ('TREF'), wherein the fraction has a block index greater than about 0.3 and up to about 1.0 and the ethylene/&agr;-olefin interpolymer has a molecular weight distribution, Mw/Mn, greater than about 1.3.

Les modes de réalisation de l'invention fournissent une classe d'interpolymères séquencés d'éthylène et d'a-oléfine. Les interpolymères séquencés d'éthylène et d'a-oléfine sont caractérisés par un indice de séquence moyen, ISM, qui est supérieur à zéro et vaut jusqu'à environ 1,0 et une distribution de masse moléculaire, Mm/Mn, supérieure à environ 1,3. De préférence, l'indice de séquence vaut d'environ 0,2 à environ 1. En plus ou en variante, l'interpolymère séquencé d'éthylène et d'a-oléfine est caractérisé par le fait d'avoir au moins une fraction obtenue par fractionnement par température croissante d'élution (« FTCE »), la fraction ayant un indice de séquence supérieur à environ 0,3 et valant jusqu'à environ 1,0 et l'interpolymère d'éthylène et d'a-oléfine ayant une distribution de masse moléculaire, Mm/Mn, supérieure à environ 1,3.
