PURPOSE: To obtain a polypropylene resin compsn. which can be molded with a good moldability by calendering into a sheet or film having little nonuniformity in thickness, good appearance and heat resistance, and such a softness as that of a plasticized polyvinyl chloride sheet or film. CONSTITUTION: This compsn. is prepd. by compounding 0.01-5 pts.wt. compd. such as an octyltin fatty acid salt, an alkylenebis fatty acid amide, or a polyhydric alcohol fatty acid ester into 100 pts.wt. polypropylene resin which comprises 100-20wt.% propylene homopolymer and/or copolymer having a ratio of rrrr/(1-mmmm)×100 in a pentad fraction by<13> C-NMR of 20-60%, a fusion peak temp. by DSC of 150 deg.C or higher, and a fusion enthalpy of 100J/g or lower, the copolymer contg. 4wt.% or lower olefin units other than propylene units, and 0-80wt.% propylene copolymer contg. 10-80wt.% olefin units other than propylene units. |
