Patent ID: 7759427

Claim:
A method for preparing a vulcanizable elastomer composition comprising the steps of: (1) mixing a cross-linkable functionalized polyethylene with at least one cross-linkable liquid elastomer to form a non-reactive extrudant, wherein the mixing occurs at a temperature in the range of 10° F. above or below the melt point of the cross-linkable functionalized polyethylene, and wherein the non-reactive extrudant contains from 20 to 80 parts per hundred of the cross-linkable liquid elastomer, (2) extruding the non-reactive extrudant, and (3) mixing the extrudent with at least one curing agent, wherein the mixing is sufficient to form the vulcanizable elastomer, and wherein the vulcanizable elastomer has a complex dynamic viscosity of less than 5 McP (5,000 N*s/m 2 ) for at least 2 minutes at a maximum flow temperature.
