<P>PROBLEM TO BE SOLVED: To provide an ethylenic polymer composition capable of being used in high-speed drawn film-forming. <P>SOLUTION: This ethylenic polymer composition for the high-speed drawn film-forming contains an ethylenic polymer in an amount of 35-60 mass% and an inorganic filler in an amount of 65-40 mass%, wherein the ethylenic polymer contains a branched-type low-density polyethylene in an amount of 3-20 mass% and is composed so that an elution component (component A) having an elution temperature of not less than 95°C and less than 120°C, an elution component (component B) having an elution temperature of not less than 85°C and less than 95°C, an elution component (component C) having an elution temperature of not less than 70°C and less than 85°C, and an elution component (component D) having an elution temperature of less than 70°C are contained in the olefinic polymer in amounts of 10-20 wt%, 20-40 wt%, 25-45 wt%, and 15-30 wt%, respectively, provided that the components A, B, C, and D are contained in an amount of 100 wt% in total, when the elution components having the specified temperature ranges are determined based on a curve relating the elution temperature to the amount of the elution component due to a continuous temperature-rising elution fractionation (TREF) method. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
