MODIFIED PROPYLENE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a flexible, oilproof propylene resin composition. SOLUTION: The resin composition comprises a polypropylene polymer (A) having a melting point measured by a differential scanning calorimeter (DSC) of 120-170°C and a propylene polymer (B) having a melting point measured by a differential scanning calorimeter (DSC) of <120°C or not having a melting point in a mass ratio (A):(B) of (5-40):(60-95) (mass%) (provided that (A)+(B)=100 mass%). The modified propylene resin composition (C) has a surface hardness (shore D) measured for a press sheet of ≤40 and contains 0.010-15 pts.mass polar monomer (M) based on 100 pts.mass total of the propylene polymer (A) and the propylene polymer (B) ((A)+(B)).
