Process for the preparation of a resin composition comprising a thermoplastic resin and an aluminum-containing inorganic compound

摘要

A resin composition comprising a thermoplastic resin and an aluminum-containing inorganic compound, wherein the thermoplastic resin and the aluminum-containing inorganic compound form a parent phase and a dispersed phase, respectively, and the following inequality (1) <DF NUM="(1)">0< d ≤ -0.0997 phi + 2.97 </DF> is satisfied, in which d ( mu m) is the wall-to-wall distance of the dispersed phases and phi (% by weight) is the content of the aluminum-containing inorganic compound based on the weight of the resin composition, is produced by melt-blending a thermoplastic resin with an aluminum-containing inorganic compound powder having a BET specific surface area of from 30 to 500 m<2>/g, a maximum particle diameter of not more than 20 mu m, and a pore volume of pores having a radius of from 50 to 1000 nm measured by mercury porosimetry of not less than 0.3 cm<3>/g.
