<P>PROBLEM TO BE SOLVED: To provide an ethylenic polymer composition which has satisfactory extrusion moldability by mixing a processability modifier having excellent molding processability-improving effect as well as a satisfactory drawdown property to an ethylenic polymer. <P>SOLUTION: The ethylenic polymer composition includes: 50-95 wt.% of an ethylenic polymer (A) selected from the group consisting of high-density polyethylene, ethylene-α-olefin copolymer composed of a repeating unit derived from 3-8C α-olefin, and high-pressure process low-density polyethylene satisfying (a); and 5-50 wt.% of a high-pressure process low-density polyethylene (B), the high-pressure process low-density polyethylene (B) satisfying (b)-(d). (a) The ratio Mw/Mn of weight average molecular weight Mw to number average molecular weight Mn is less than 6, (b) Mw/Mn is 6 or more, (c) MFR is 1-10 g/10 min., and (d) the chemical emission intensity after 5 minutes from measurement start, which is measured at 95°C, is 40 counts/sec. or more per g of pellet. <P>COPYRIGHT: (C)2013,JPO&INPIT |
