FIELD: chemistry.SUBSTANCE: invention relates to a hydrogenated block copolymer, a polypropylene resin composition and a moulded article. Described is a hydrogenated block-copolymer containing in its molecule a polymer block (C) having a diene compound with conjugated double bonds as a main component, polymer block (B) having a diene compound with conjugated double bonds as a main component, and polymer block (S) having a vinylaromatic compound as the main component. Polymer unit (B) comprises polymer units (B1) and (B2).EFFECT: polypropylene resin composition containing the disclosed hydrogenated block-copolymer has excellent balance of fluidity, stiffness, impact strength and appearance after moulding.20 cl, 15 tbl, 21 ex, 4 dwg |
