Ionomers based on ethylene/unsaturated carboxylic acid copolymers are modified with from 0.5 to 15 weight percent adipic acid. The modified-ionomers have improved melt flow and melt processing behavior over unmodified ionomers having a comparable level of neutralization of acid groups present. Certain mechanical properties are improved, particularly stiffness, abrasion resistance and low temperature izod impact. |
