Abstract
A composite elastic material is provided having improved hysteresis comprising a layer of an elastic material bonded to a layer of nonelastic material at least one side. The elastic material layer is made from a blend of a narrow polydispersity number polymer and a conventional elastomer, and the blend is essentially free of low molecular weight polyethylene processing aids. The composite elastic material laminate should have a hysteresis at least 15 percent better than a similar laminate made without the narrow polydispersity number elastomer but with the processing aid.
