Abstract:
A polypropylene resin composition which is obtained by blending (A) 100 parts by weight of a polypropylene resin comprising (a) 100 to 20% by weight of a homopolymer of propylene and/or a propylene copolymer containing 4% by weight or less of another olefin unit in which (i) in a pentad fraction by an isotope carbon nuclear magnetic resonance spectrum (.sup.13 C-NMR), [rrrr/(1-mmmm)].times.100 is in the range of 20 to 60%, (ii) a melt peak temperature (Tm) measured by a differential scanning calorimeter (DSC) is 150.degree. C. or more, and (iii) a melt enthalpy (.DELTA.H) measured by DSC is 100 J/g or less, and (b) 0 to 80% by weight of a propylene copolymer containing 10 to 80% by weight of an olefin unit other than propylene, with (B) 0.01 to 5 parts by weight of at least one fatty acid derivative selected from the group consisting of octyltin salts of fatty acids, alkylenebisfatty acid amides, fatty acid esters of polyvalent alcohols, and metal salts of aliphatic monocarboxylic acids.
