Abstract:
1. A propylene polymer resin composition, comprising: 50% to 99% by weight of a propylene polymer resin; and 1% to 50% by weight of an ethylene polymer resin, wherein the ethylene polymer resin has: (A) a density (d), as measured by a density gradient tube method according to JIS K6760, in the range of 940 kg/m (B) a melt flow rate (MFR), as measured at 190° C. under a load of 2.16 kg, in the range of 1 g/10 min. to 10 g/10 min.; (C) a frequency of terminal vinyl of not more than 0.2 per 1,000 carbon atoms; (D) a melt strength (MS (E) an activation energy of flow (Ea) of not larger than 35 kJ/mol, and wherein the propylene polymer resin composition satisfies a relationship between a melt strength (MS wherein MS MFR is a melt flow rate (g/10 min.) as measured at 190° C. under a load of 2.16 kg.
