PROBLEM TO BE SOLVED: To produce the subject composition, having a high melt tension and excellent in molding processability by blending an olefin (co)polymer prepared by using a metallocene catalyst system with an olefin polymer. SOLUTION: This composition comprising (I) 99-50 wt.% olefin polymer, prepared by (co)polymerizing an olefin using a catalyst composed of (A) a transition metallic compound having aπ-electron conjugated ligand, (B) one or more compounds selected from an aluminoxane, an ionic compound reactive with the compound A and forming an ionic complex and a Lewis acid and (C) an organoaluminum compound and having 0.2-10 dL/g intrinsic viscosity [η1 ] measured in tetralin at 135 deg.C and (II) 1-50 wt.% olefin polymer consisting essentially of 0.01-5 pts.wt. high-molecular weight olefin polymer having 15-100 dL/g intrinsic viscosity [ηE] measured in tetralin at 135 deg.C and 100 pts.wt. olefin polymers other than the high-molecular weight olefin polymer. |
