Title (EN) HETEROGENEOUS ETHYLENE ALPHA-OLEFIN INTERPOLYMER
(FR) INTERPOLYMÈRE HÉTÉROGÈNE D'ÉTHYLÈNE ET D'ALPHA-OLÉFINE
Abstract:
(EN) An interpolymer of ethylene and at least one alpha-olefin is claimed, wherein the ethylene interpolymer is characterized as having an average Mv and a valley temperature between the interpolymer and high crystalline fraction, Thc, such that the average Mv for a fraction above Thc from ATREF divided by average Mv of the whole polymer from ATREF (Mhc/Mp) is less then about 1.95 and wherein the interpolymer has a CDBI of less than 60%. The interpolymer of ethylene and at least one alpha-olefin can also be characterized as having a high density (HD) fraction and an overall density such that % HD fraction < -2733.3 + 2988.7x + 144111.5 (x - 0.92325)2 where x is the density in grams/cubic centimeter. Fabricated articles comprising the novel interpolymers are also disclosed.
(FR) La présente invention concerne un interpolymère d'éthylène et d'au moins une alpha-oléfine, ledit interpolymère d'éthylène étant caractérisé en ce qu'il présente un volume moyen et une température minimale, située entre celle de la fraction interpolymère et celle de la fraction hautement cristalline, Thc, tels que le volume moyen pour une fraction située au-dessus de la Thc, comme déterminé par ATREF, divisé par le volume moyen du polymère entier, comme déterminé par ATREF, (Mhc/Mp) est inférieur à environ 1,95, tandis que le CDBI de l'interpolymère est inférieur à 60 %. Ledit interpolymère d'éthylène et d'au moins une alpha-oléfine peut également être caractérisé comme présentant une fraction de haute densité (HD) et une densité globale telles à ce que le % de la fraction HD est inférieur à -2 733,3 + 2 988,7x + 144 111,5 (x - 0,92325)2 où x représente la densité en grammes/centimètre cube. La présente invention concerne également des objets fabriqués contenant lesdits interpolymères inédits.
