Polyethylene resin composition.

摘要

A polyethylene resin composition having improved moldability and comprising: (A) 50-99.9 parts by weight of an ethylene polymer; and (B) 0.1-50 parts by weight of a modified ethylene- alpha -olefin copolymer obtained by fluorinating an ethylene- alpha -olefin copolymer having the following properties (i) to (iv), said ethylene- alpha -olefin copolymer being prepared by copolymerizing ethylene with an alpha -olefin having 3 to 12 carbon atoms in the presence of a catalyst comprising a solid catalyst component and an organoaluminum compound, said catalyst component containing at least magnesium and titanium: (i) Melt index : 0.01-100 g/10 min (ii) Density : 0.860-0.910 g/cm<3> (iii) Maximum peak temperature (Tm) as measured according to differential scanning calorimetry (DSC) : not lower than 100 DEG C (iv) Boiling n-hexane insolubles content : not lower than 10 wt.%
