Title:
THERMOPLASTIC ELASTOMER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2005/033199
Kind Code:
A1
Abstract:
The invention provides a novel thermoplastic elastomer composition which is well balanced between hardness and mechanical strengths and is excellent over a wide temperature range in rubber elasticity, creep performance at high temperature, processability in molding, oil resistance, and heat resistance, that is, a thermoplastic elastomer composition comprising (A) a (meth)acrylic block copolymer, (B) a compound having two or more amino groups in the molecule, and (C) a thermoplastic resin, characterized in that the (meth)acrylic block copolymer (A) is composed of (A1) a (meth)acrylic copolymer block and (A2) an acrylic copolymer block, at least either of which has at least one acid anhydride group in the backbone chain, and that the (meth)acrylic block copolymer (A) and the compound (B) are dynamically crosslinked in the thermoplastic resin (C).
