Title: PROPYLENE POLYMER RESIN COMPOSITION
Abstract:
Provided is a propylene polymer resin composition having a high melt tension, improved fluidity, and excellent workability, which comprises 99 to 50 wt% of propylene polymer resin and 1 to 50 wt% of ethylene polymer resin which satisfies the following (A) through (E): (A) Density (d) as determined by the density gradient tube method in accordance with JIS K6760 is between 940 kg/m3 and 960 kg/m3. (B) The melt flow rate (MFR) as determined under 190°C and a load of 2.16 kg is between 1 g/10 minutes and 10 g/10 minutes. (C) The number of terminal vinyl groups is no greater than 0.2 per 1,000 carbon atoms. (D) The melt tension as determined at 160°C (MS160) is 100 mN or greater. (E) The flow activation energy (Ea) is 35 kJ/mol or less.
