Abstract:
A thermoplastic resin composition containing a thermoplastic resin (A) and a silane-treated foliated phyllosilicate (B), wherein the composition is prepared by:expanding a basal spacing of a swellable layered silicate (B1) in a dispersion medium;introducing a organosilane compound (B2) represented by general formula (I):Y.sub.n SiX.sub.4-n (I)wherein n denotes an integer of 0 to 3, Y denotes independently a substituted or non-substituted hydrocarbon group having 1 to 25 carbon(s), and X denotes independently a hydrozable group or a hydroxyl group, into the swellable layered silicate (B1) in the dispersion medium to prepare a dispersion,mixing the dispersion with a monomer of the thermoplastic resin (A) to prepare a mixture, andpolymerizing the polymer, wherein:a value {R.sub.B300 } is 20% or more than the value {R.sub.B300 } is defined as a rate of layers of the silane-treated foliated phyllosilicate (B) of which equivalent area circle diameter {D} is 300 nm or less.
