PROPYLENE RESIN COMPOSITION AND ITS MELDED ARTICLE

摘要

PURPOSE: To obtain a propylene resin composition having low-temperature fluidity and excellent stampable moldability. CONSTITUTION: This propylene resin composition is prepared by dynamically heat-treating a blend comprising (A) 100 pts.wt. of a propylene-α-olefin block copolymer having a ratio (η1 /η2 ) of melt viscosityη1 at 10<1> sec-<1> shear rate and melt viscosityη2 at 10<2> sec-<1> shear rate of 3.5-8 measured by a slit die method, (B) 1-30 pts.wt. of at least one plasticizer selected from a mineral oil-based softening agent, a phthalic acid ester-based plasticizer and a silicone oil and (C) 0.005-2 pts.wt. of an organic peroxide to adjust the melt flow rate to 50-300g/10 minutes.
