Title:
THERMOPLASTIC ELASTOMER COMPOSITION
Document Type and Number:
Japanese Patent JP3516387
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a thermoplastic resin which can be processed for two-color forming with ABS resin in a manner similar to that for P.V.C. normally used for the above purpose and has excellent adhesive strength.
SOLUTION: This thermoplastic elastomer composition comprises the following 3 components (a) to (c): (a): 5 to 60 wt.% of a hydrogenated block copolymer obtained by hydrogenating a block copolymer composed of a terminal polymer block A with at least two vinyl aromatic compounds as the major components and intermediate block B with at least one conjugated diene compound as the major component, (b) 1 to 20 wt.% of a hydrogenated block copolymer modified with a polar group, the hydrogenated block copolymer being obtained by hydrogenating a block copolymer composed of a terminal polymer block A with at least two vinyl aromatic compounds as the major components and intermediate block B with at least one conjugated diene compound as the major component, and (c): 3 to 60 wt.% of a copolymer of propylene and a 2-8C α- olefin, and (d): 20 to 90 wt.% of a copolymer of ethylene, carbon monoxide and an alkyl acrylate ester.
