POLYPROPYLENE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain the subject composition excellent in impact resistance, rigidity and heat resistance. SOLUTION: This resin composition 0.5-300g/10min in MFR determined in accordance with the JIS K-7210 comprises (A) 70-95wt.% of a homopolypropylene component 0.01-1000g/10min in MFR satisfying the relationship:ΔHm >=24.50+1.583logMFR (ΔHm is heat of fusion determined by differential scanning colorimetry) and (B) 5-30wt.% of a propylene-ethylene copolymer component 30-80wt.% in ethylene content and 2-6dl/g in intrinsic viscosity.
