Abstract

PURPOSE: The title composition having improved blocking resistance without loss of transparency, obtained by blending polypropylene with a blend of finely divided hydrophobic silica having specific particle diameters with finely divided inorganic powder in a specified blending ratio.
CONSTITUTION: A) Polypropylene is blended with B) 0.01W1.0 wt. %, preferably 0.03W0.5 wt. % of a blend of finely divided inorganic powder in a twin-cylinder mixer, etc. B) The blend of finely divided organic powder is obtained by mixing a) finely divided hydrophobic silica, e.g., silica treated with trimethylchlorosilane, having an average particle diameters of 1W30 mμ, and particle sizes in the region of 1W50 mμ with b) finely divided inorganic powder (preferably silica gel) having an average particle diameter of 1W15 μ, preferably 1W10μ in a weight ratio of a) to b) of 1.0/1W2/1, preferably 0.3/1W1.5/1.
