ABSTRACT:
A thermoplastic resin composition comprising:(A) 100 parts by weight of a noncrystalline thermoplastic resin component (component A);(B) 0.1 to 50 parts by weight of a layered silicate (component B) which satisfies the following (i) to (iii):(i) it has a cation exchange capacity of 50 to 200 milliequivalents/100 g, and at least 40% of the cation exchange capacity being exchanged with an organic onium ion,(ii) 60% or more of the layered silicate particles have a thickness of 100 nm or less in the resin composition, and(iii) the interlayer spacing of the layered silicate (component B) in the resin composition is smaller than the interlayer spacing of the layered silicate alone by 0.5 nm or more; and(C) 0 to 50 parts by weight of a compound (component C) having affinity for the noncrystalline thermoplastic resin component as the component A and a hydrophilic component; andmolded articles thereof.According to the present invention, a noncrystalline thermoplastic resin composition having excellent stiffness, surface appearance and heat stability, especially a polycarbonate resin composition and molded articles thereof are obtained.
