Patent ID: 7985804

Claim:
A composition comprising: (a) from about 11 to about 35 weight % of a first component, wherein said first component is a mEPDM low density modifier having a branching index of at least 0.7, and an Mw of 500,000 g/mole or more, said mEDPM low density modifier comprising: i) 10 to 30 weight percent semi crystalline minor component having 40 to 77 weight percent ethylene derived units; 0 to 10 weight percent diene derived units; and alpha-olefin derived units having 3 to 10 carbon atoms making up the remainder of the minor component; and ii) 70 to 90 weight percent amorphous major component having 60 to 70 weight percent ethylene derived units; 0 to 10 weight percent diene derived units; and alpha olefin derived units having 3 to 10 carbon atoms making up the remainder of the major component; wherein the viscosity of the major component is less than one fourth the viscosity of the minor component, and wherein the mEPDM has a diene content of at least 0.5 weight percent based on the total weight of the mEPDM; and (b) from about 89 to about 65 weight % of a second component, wherein said second component is selected from a mLLDPE having a density ranging from about 0.910 to about 0.940 g/cc, an HDPE having a density ranging from about 0.940 g/cc and less than 0.970 g/cc, or a mixture thereof; wherein the weight % is based on the total weight of said first component and said second component.
