HETEROGENEOUS ETHYLENE ALPHA0OLEFIN INTERPOLYMER.

摘要

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.
