PROBLEM TO BE SOLVED: To provide a polystyrene-based thermoplastic elastomer which has excellent scratch resistance, namely excellent abrasion resistance, further excellent coatability, excellent solvent adhesivity, excellent printability, and so forth. SOLUTION: This polystyrene-based thermoplastic elastomer composition comprising (A) a thermoplastic resin consisting essentially of a polystyrene-based resin, (B) a partially or perfectly crosslinked rubbery polymer comprising an aromatic vinyl/conjugated diene block copolymer and/or a hydrogenated aromatic/conjugated diene random copolymer and, if necessary, (C) a compatibilizing agent, wherein the components (B) and (C) in the composition are 40 to 90 pts.wt. and <40 pts.wt., respectively, per 100 pts.wt. of [the component (A) + the component (B) + the component (C)]. |
