摘要：
polypropylene resin composition comprises 100 parts by weight of propylene homopolymer having a stereoregularity of a boiling heptane-insoluble part thereof of not less than 0.960 as an isotactic pentad rate obtained by 13 C-NMR, and 0.01 to 2 parts by weight of a hydrocarbon polymer having completely or partially saturated main hydrocarbon chain and at least one hydroxy group at an end of the main hydrocarbon chain, and is used to produce a biaxially stretched film having an improved combination of properties.
