A polyolefin-based resin composition comprising (A) 100 parts by weight of a polyolefin-based resin, (B) 10 to 200 parts by weight of a metal hydroxide powder, (C) 0.01 to 50 parts by weight of a powdery material consisting of (i) a liquid organopolysiloxane having at least one silicon-bonded hydrogen atom per molecule and (ii) an inorganic powder other than a metal hydroxide, and (D) a platinum-based catalyst in an amount sufficient to provide 0.1 to 10,000 ppm of platinum metal based on the total weight of component (A) and component (B); and a process for the production thereof.
A polyolefin-based resin composition comprising (A) 100 parts by weight of a polyolefin-based resin, (B) 10 to 200 parts by weight of a metal hydroxide powder, (C) 0.01 to 50 parts by weight of a powdery material consisting of (i) a liquid organopolysiloxane having at least one silicon-bonded hydrogen atom per molecule and (ii) an inorganic powder other than a metal hydroxide, and (D) a platinum-based catalyst in an amount sufficient to provide 0.1 to 10,000 ppm of platinum metal based on the total weight of component (A) and component (B).
A process for preparation of a polyolefin-based resin composition comprising mixing under heating (A) 100 parts by weight of a polyolefin-based resin and (B) 10 to 200 parts by weight of a metal hydroxide powder, and then mixing therein (C) 0.01 to 50 parts by weight of a powdery material consisting of (i) a liquid organopolysiloxane having at least one silicon-bonded hydrogen atom per molecule and (ii) an inorganic powder other than a metal hydroxide and (D) a platinum-based catalyst in an amount sufficient to provide 0.1 to 10,000 ppm of platinum metal based on the total weight of component (A) and component (B).
