Patent ID: 6984695

Claim:
A heterogenized/homogeneous polymer composition comprising: A) from 90 to 98 eight % of a first polymer fraction having a density of from 0.880 to 0.945 grams per cubic centimeter as measured by ASTM D792; a melt index, I 2 , of from 0.1 to 200 grams per 10 minutes as determined by ASTM D1238; less then 2 weight % hexane extractables; and a substantial absence of homopolymer wherein said first polymer fraction comprises at least one homogeneous copolymer of ethylene and at least one C 4 to 10 alpha olefin, and wherein each of said at least one homogeneous copolymer is characterized by having a molecular weight distribution, Mw/Mn, of less then three; and B) from 2 to 10 weight % of a second polymer fraction having a higher molecular weight, Mw, than that of said first fraction; a higher density than said first fraction; and a lower alpha olefin content than said first fraction, wherein said second polymer fraction comprises at least one second homogeneous polymer of ethylene, optionally with at least one C 4 to 10 alpha olefin comonomer, and wherein each of said at least one second homogeneous polymer of ethylene is characterized by having a molecular weight distribution, Mw/Mn, of less than 3, and by having less than 4 short chain branches per 1,000 carbon atoms.
