Abstract
A thermoplastic resin composition includes 1 to 200 parts by weight of an inorganic filler (C) blended with 50 to 80 parts by weight of a thermoplastic resin (A) and 20 to 50 parts by weight of a rubbery polymer having a reactive functional group (B) which together account for 100 parts by weight; wherein the thermoplastic resin (A) and the rubbery polymer having a reactive functional group (B) form a continuous phase and a dispersed phase, respectively, while the inorganic filler (C) is dispersed in the continuous phase and/or the dispersed phase; and the dispersed phase of the rubbery polymer contains fine particles with a diameter of 1 to 100 nm of a compound resulting from a reaction between the thermoplastic resin (A) and the rubbery polymer; and an area occupied by the fine particles account for 10% or more of the dispersed phase.
