Thermoplastic elastomeric compositions

摘要

Grafted thermoplastic elastomer compositions formed by melt blending of a minor proportion of a thermoplastic material having a high softening point with a minor proportion of a glycidyl-containing copolymer, followed by melt blending of the thermoplastic material/glycidyl-containing copolymer blend with a major proportion of an acid-containing ethylene copolymer have a unique combination of unexpectedly good high temperature properties, compression set resistance and/or rebound.
