PROPYLENE-BASED ELASTOMERIC COMPOSITION |
摘要 |
<p>The present invention includes a polyolefin elastomeric composition comprising a propylene-based elastomer having at least seventy five weight percent units derived from propylene, the propylene-based elastomer exhibiting a heat of fusion of from 1 to 35 Joules/gram, a weight average molecular weight of from 5400 to 875000 g/mol, and a permanent set of less than 40%; and a homogeneous ethylene-alpha olefin interpolymer having a molecular weight distribution of less than 3.5, a density from 0.885 to 0.915 g/ml, and a heat of fusion of from 65 to 125 Joules/gram, wherein the ratio of the propylene-based elastomer to the homogeneous ethylene-alpha olefin interpolymer is from 97:3 to 80:20, and wherein the composition exhibits a heat of fusion from 2 to 55 Joules/gram, and a 2% secant flexural modulus of less than 69 MPa.</p> |
