Abstract
An elastomeric composition comprising: PA1 (A) a polyester elastomer; PA1 (B) a thermoplastic polyurethane elastomer; and PA1 (C) a multiphase composite interpolymer comprising an elastomeric first phase, a final rigid thermoplastic phase and, optionally, one or more intermediate phases, wherein components (A) and (B) combined are present in the composition in an amount of from about 55 to about 90 percent by weight, based on the total weight of components (A), (B) and (C); and wherein the ratio by weight of component (A) to component (B) is from about 1:5 to about 8:1.
