Abstract

PURPOSE: The titled composition, having improved moldability, appearance, flexibility, etc. and greatly improved transparency without stress-whitening, and prepared by blending a specific propylene copolymer with a specific rubberlike copolymer.
CONSTITUTION: 20W95wt% propylene/hexene-1 copolymer with a hexene-1 content of 10W20wt%, preferably a density of 0.890 or less, and a melt flow rate of 0.1W 30 is blended with 80W5wt% ethylene/propylene bipolymer rubber and (or) ethylene/propylene/nonconjugated diene terpolymer rubber of propylene content 15W 20wt% and gel fraction (in cyclohexane at 30°C) 10W60wt%, usually a terpolymer rubber containing 15wt% or less 1,4-hexadiene, etc. as the nonconjugated diene.
