Propylene (co)polymer composition using metallocene catalyst

摘要

The present invention provides a polypropylene composition having a high melt tension and an excellent formability by blending polypropylene (I) produced with a metallocene catalyst type and an olefin (co)polymer (II) comprising 0.01 to 5 parts by weight of the following component (II-1) and 100 parts by weight of the following component (II-2); (II-1): an ethylene homopolymer or an ethylene-olefin copolymer comprising at least 50 wt % ethylene polymerization units, which is a high molecular weight polyethylene having an intrinsic viscosity [etaE] measured in tetralin at 135° C. of 15 to 100 dl/g; and (II-2): polypropylene.
