A POLYETHYLENE BLEND COMPOSITION AND FILM MADE THEREFROM

摘要

A polyethylene blend composition suitable for film applications comprising from 10 to 100 percent by weight of an ethylene -based polymer made by the process of: selecting an ethylene/a- olefin interpolymer (LLDPE) having a Comonomer Distribution Constant (CDC) in the range of from 75 to 300, a vinyl unsaturation of less than 150 vinyls per one million carbon atoms of the ethylene/a-olefin interpolymer; a zero shear viscosity ratio (ZSVR) in the range from 4 to 50; a density in the range of from 0.925 to 0.950 g/cm3, a melt index (I2) in a range of from 0.1 to 2.5 g/ 10 minutes, a molecular weight distribution (Mw/Mn) in the range of from 1.8 to 4.0; reacting said ethylene/α-olefin interpolymer with an alkoxy amine derivative in an amount equal to or less than 900 parts derivative per million parts by weight of total ethylene/α-olefin interpolymer under conditions sufficient to increase the melt strength of the ethylene/α-olefin interpolymer is provided.
