摘要： A thermoplastic resin composition containing inorganic particles, wherein (i) the inorganic particles have pore volume of 0.1 to 3 ml/g and (ii) the inorganic particles are treated at the surfaces with a hydrophilic polyester of 0.05 to 10 times the weight of the inorganic particles or with a silicon-containing organic compound. This composition can be obtained by feeding a dispersion of the above-mentioned surface-treated inorganic particles into a vented double-screw kneader and extruder to mix it with a thermoplastic resin.
