<p>PROBLEM TO BE SOLVED: To provide a polyethylene composition which has excellent transparency, moldability and heat distortion resistance and shows reduced surface gloss deterioration caused by adhesion to the mold on injection molding. SOLUTION: This polyethylene composition comprises 100 pts.wt. of the resin components containing (A) 99-60wt.% of an ethylene-α-olefin copolymer which is polymerized by a catalyst system containing a transition metal (Ti, Zr or HF), having(a) a melt flow rate (MF) of 0.3-80g/10min, (b) a density of 0.86-0.925g/cm<3> and (c) a plurality or single of DSC peaks at <=120 deg.C and (B) 1-40wt.% of an ethylene homopolymer or an ethylene-α-olefin copolymer other than above-stated copolymer, having one DSC peak at >=120 deg.C, MF of 0.01-5.0g/10min, density of 0.93-0.965g/cm<3> and (C) 0.002-2 pts.wt. of a nucleating agent. The composition has the MF of 0.05-60g/10min. and the density of 0.880-0.935g/cm<3> .</p> |
