Abstract

PURPOSE: To prepare the title composition having excellent processability and fluidity and giving a highly transparent molded article without pelletization, by compounding granular polypropylene with a specific amount of a lubricant to attain an apparent density higher than a definite value.
CONSTITUTION: (A) 100pts.wt. of granular polypropylene which gives an apparent density higher than a definite value after compounding with a lubricant, i.e. represented by the formula [100≤Dp≤12,000, R(Dp)=0W100, 100≤De≤800, n≥2.5], is compounded with (B) 0.01W0.6pt. of a lubricant (a metal salt of a saturated fatty acid and a fatty acid amide), to obtain the objective composition having an apparent density of ≥0.55g/ml. The composition may contain a heat-stabilizer, etc.
