ABSTRACT:
Novel thermoplastic elastomer compositions, made by dispersing a polyolefin elastomer phase containing functionalized EPM or EPDM in a polyamide resin followed by cross-linking of the elastomer phase, are described. The cross-linked phase exists as discreet particles, providing an overall blend which remains thermoplastic. The resulting blend may be used in the fabrication of elastomeric goods without the need for a separate vulcanization step after the desired object is formed.
