RUBBER-BASED POLYMER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a rubber-based polymer composition excellent in scratch resistance, oil resistance and mechanical strengths. SOLUTION: The crosslinked rubber-based polymer composition comprises (A) a hydrogenated copolymer (A-1) having ≤2J/g crystallization peak calorie in Differential Scanning Calorimetry (DSC method) and obtained by hydrogenating a copolymer composed of a conjugated diene-based monomer having ≥5 wt.% and ≤90 wt.% aromatic vinyl monomer content and one or more kinds of crosslinkable rubber-like polymers (A-2) selected from (a1) a copolymer composed of ethylene and 3-20C α-olefin and (a-2) a hydrogenated rubber obtained by hydrogenating a copolymer composed of a conjugated diene-based monomer having <5 wt.% aromatic vinyl monomer content and an aromatic vinyl monomer and (B) a thermoplastic resin.
