The present invention provides a thermoplastic polymer composition that is excellent in transparency and excellent in properties such as rigidity, hardness, and heat resistance, a method for producing the same, and a molded article comprising the thermoplastic polymer composition. A liquid thermoplastic polymer mixture containing a transparent thermoplastic polymer, inorganic fine particles having an average particle size of 50 nm or less, and an organic solvent is exposed to a supercritical fluid and / or a liquefied gas in a pressurized environment. Thereafter, the pressure environment is reduced to vaporize the supercritical fluid and / or liquefied gas and remove the organic solvent to produce a thermoplastic polymer composition having excellent transparency, rigidity, hardness and heat resistance. .
