PURPOSE:To obtain the subject composition excellent in strength and breaking characteristics by blending a composition composed of an olefinic resin, a PS- based resin and an inorganic filler in a specific proportion with a prescribed amount of a styrene-ethylene-butylene-styrene block copolymer elastomer, etc. CONSTITUTION:The objective composition is obtained by blending (A) 100 pts.wt. composition of (i) 65-20wt.% olefinic resin such as PP, (ii) 5-30wt.% styrene-based resin and (iii) 30-50wt.% inorganic filler such as talc with (B) 0.05-10 pts.wt. styrene-ethylene-butylene-styrene block copolymer elastomer and/ or styrene- ethylene-propylene-styrene block copolymer elastomer. |
