Abstract:
A polymer blend composition comprising:(a) from about 1 to about 3 weight percent of an autoclave process produced ethylene homopolymer having a density of from about 0.915 to about 0.925 grams per cubic centimeter (g/cc), a molecular weight distribution (Mw/Mn) of from about 9 to about 15, and a melt index of from about 1 to about 4 grams per 10 minutes (g/10 min); and(b) from about 97 to about 99 weight percent of a gas phase polymerization process produced linear ethylene-alpha olefin copolymer, wherein the alpha-olefin comonomer is present in an amount of from about 5 to about 12 weight percent based upon the copolymer and has about 3 to about 20 carbon atoms, the copolymer having a molecular weight distribution (Mw/Mn) of not greater than 6, a density of from about 0.90 to about 0.925 grams per cubic centimeter (g/cc), and a melt index of from about 0.3 to about 4.0 grams per 10 minutes (g/10 min),wherein said weight percents are based on the total weight of said ethylene homopolymer (a) and said linear ethylene-alpha olefin copolymer (b).
