摘要： A thermoplastic elastomer blend, which comprises 15 to 85% by weight of a cross-linked acrylic rubber-dispersed polyamide-based thermoplastic elastomer, and 85 to 15% by weight of a polyester-based thermoplastic elastomer, or which comprises 20 to 90% by weight of a cross-linked acrylic rubber-dispersed polyamide-based thermoplastic elastomer, and 80 to 10% by weight of a polyamide-based thermoplastic elastomer. The cross-linked acrylic rubber-dispersed polyamide-based thermoplastic elastomer is used also as a blend with both of the polyester-based thermoplastic elastomer and the polyamide-based thermoplastic elastomer. The thermoplastic elastomer blend is effectively used as joint boot-molding material, etc., having distinguished heat resistance and low temperature characteristics, applicable also to the joint boot inboard side.

摘要： A joint boot molded from an acrylic rubber/polyamide-based thermoplastic elastomer, which comprises a polyamide resin and a cross-linked acrylic rubber. The acrylic rubber/polyamide-based thermoplastic elastomer is a dispersion of the rubber in the polyamide resin, obtained by dynamic cross-linking of the acrylic rubber, preferably by covalent bond-linkable cross-linking of the polyamide resin with the acrylic rubber. The joint boot has a fully satisfactory heat resistance required even for use at the inboard side.
