PURPOSE: To obtain a resin compsn. for extrusion which gives an extrudate improved in the strengths of the part where two resin flows have joined each other in a die in extrusion blow molding or in pipe extrusion. CONSTITUTION: This resin compsn. comprises 60-95 pts.wt. propylene polymer having an MFR of 0.1-5g/10min and a density of 0.890-0.915g/cm<3> , 5-30 pts.wt. linear low-density polyethylene having an MFR of 0.1-10g/10min, a density of 0.910-0.935g/cm<3> , and a Q value of 5 or higher, and 1-15 pts.wt. ethylene-α- olefin copolymer elastomer having an MFR of 0.1-10g/10min and a density of 0.840-0.900g/cm<3> . |
