PURPOSE:To obtain a propylene resin composition having high rigidity, high impact resistance, good processability and good quality stability. CONSTITUTION:The composition comprises 100 pts.wt. polypropylene and 1-60 pts.wt. product obtained by decomposing with an organic peroxide a propylene block copolymer comprising 0.01-5wt.% polybutene component, 1-70wt.% polypropylene component and 25-98.99wt.% propylene/ethylene random copolymer component comprising 15-80mol% units derived from ethylene and 85-20mol% units derived from propylene and having a content of a component of a molecular weight of 10000 or below of 1.0wt.% or below and a weight-average molecular weight of 600000 or above. |
