Abstract

PURPOSE: The titled composition that is made by kneading a moidified polypropylene, resulting from treating a crystalline polypropylene with an organosliane and an organic peroxide, together with a calcined caolin and an aminosilane, thus giving molded products with high surface hardness and surface smoothness.
CONSTITUTION: The objective composition is produced by combining (A) a modified polypropylene that is prepared by mixing 100pts.wt. of a crystalline polypropylene, preferably a propylene-ethylene block copolymer, with 0.1W3pts. of an organosilane having ethylenically unsaturated bonds such as vinyltrimethoxysilane and 0.1W0.5pts. of an organic peroxide such as t-butylperoxy acetate and by heat treating them, in which the polypropylene may contain less than 90% of unmodified polypropylene, with (B) 0.05W3pts. of an aminosilane for treating the surfaces of the calcined caolin such as α-aminoethyltriethoxysilane and (C) 100pts. of calcined caolin such as caolinite, when necessary, further together with other additives and by mixing them under melting.
