Patent ID: 7776987

Claim:
A composition comprising a polymeric material having a rheology such that the slope (or S) determined by linear least squares regression, of a plot of the natural kg of loss modulus (or G″) versus natural log of storage modulus (or G′) is greater than [0.635*(melt index)+13.2]/[(melt index)+16.6], and wherein the polymeric material has a CDF RI fraction less than 0.23 of a GPC chromatogram which has a molecular weight above 85,000 g/mol, and a CDF LS fraction of more than 0.07 at a conventional GPC molecular weight of 1,750,000 g/mol or greater; wherein the polymeric material has a melt index greater than 10 g/10 min and comprises an LDPE having a high molecular weight highly branched component with an MWD greater than 10 and a Mw(absolute)/Mw(GPC) ratio greater than 3.0; and where melt index is determined according to ASTM 1238 condition 190° C/2.16 Kg.
