EXTRUDED MOLDING

摘要

PROBLEM TO BE SOLVED: To provide an extrusion molding composed of a propylene-based polymer having excellent extrusion moldability and surface characteristics. SOLUTION: This extrusion molding comprises a propylene-based polymer having (a) a ratio MI49/MI21.2 of MI49 (g/10 minutes) at 230 deg.C under 49 N load to MI21.2 (g/10 minutes) under 21.2 N load and Mw/Mn measured by a GPC method satisfying a relation of formula (I) MI49/MI21.2>=0.240×Mw/Mn+3.1(I) and (b) a melt tension MS (g) at 230 deg.C and an intrinsic viscosity [η] (dl/g) in a tetralin solvent at 135 deg.C satisfying a relation of formula (II) logMS>=3.17×log[η]-0.68 (II). [η] is in the range of 0.5-3.5 dl/g.
