Abstract

PURPOSE: Titled composition which can provide films having improved SiO2 dispersibility, prepared by adding SiO2 and a specified inorganic additive to a polyolefin.
CONSTITUTION: A polyolefin composition prepared by adding, to 100pts.wt. of a polyolefin, 0.05W2pts.wt. of SiO2 and 0.05W2pts.wt. at least one inorganic additive selected from talc, pyrophyllite, kaolin and sericite in a ratio, inorganic additive/ SiO2, of 0.01W0.70. As the polyolefin which can be used preferably, there is mentioned a polypropylene having a particle size distribution represented by the expression, wherein Dp is a particle diameter, μ, R(Dp) is a wt% of particles having a diameter greater than Dp, De is a particle size characteristic number and is represented by the particle diameter when R(Dp)=36.8wt%, 100≤Dp≤1,200, R(Dp)= 0W100, 100≤De≤800 and n≥2.5, and not containing more than 1wt% of particle below 100μ and more than 1wt% of particles above 1,200μ. And the average diameters of SiO2 and the inorganic additive are 0.5W15μ, respectively.
