Vulcanized blends of thermoplastic elastomers and EPDM rubbers and process for their preparation

摘要

The present invention provides a vulcanized blend of a poly (ether imide ester) copolymer or a poly (ether-ester-amide) block copolymer with an epoxy functionalized EPDM rubber having an improved elastic recovery percentage (%). The vulcanization of the blended blends of poly (etherimide ester) copolymers or poly (ether-ester-amide) copolymers with epoxy functionalized EPDM rubbers can be carried out using crosslinking agents such as organic diamines.
