Abstract:
A propylene polymer resin composition comprising 50-99 wt. % of a propylene polymer resin and 1-50 wt. % of an ethylene polymer resin, wherein said ethylene polymer resin has the following characteristics (A) through (E): (A) a density (d), as measured by a density gradient tube method according to JIS K6760, of 940-960 kg/m3; (B) a melt flow rate (MFR), as measured at 190° C. under a load of 2.16 kg, of 1-10 g/10 min.; (C) a frequency of terminal vinyl of not more than 0.2 per 1,000 carbon atoms; (D) a melt strength (MS160), as measured at 160° C., of at least 100 mN; and (E) an activation energy of flow (Ea) of not larger than 35 kJ/mol. The propylene polymer resin has high melt strength and exhibits enhanced fluidity, processability and shapability.
