▎ 摘　　要

NOVELTY - A polyester composite comprises matrix resin and nanomaterial that is dispersed in the matrix resin, where the matrix resin is a solid dispersion of anhydrosugar alcohol in which the nanomaterial is dispersed, and ethylene glycol, butane diol, cyclohexanedimethanol or a polyester resin that is a polymerization reaction product of diol component and a dicarboxyl component containing an aliphatic diol compound and solid dispersion of anhydrosugar alcohol contains the nanomaterial in an aqueous dispersion state of an anhydrosugar alcohol. USE - A polyester composite used for molded article (claimed). ADVANTAGE - The polyester composite exhibits mechanical properties e.g., tensile strength, tensile modulus and elongation, where the nanomaterials are uniformly dispersed in the composite and have uniform properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for producing polyester composite which involves polymerization reaction of diol component and dicarboxyl component including aliphatic diol compound selected from solid dispersion of anhydrosugar alcohol in which the nanomaterial is dispersed, and aliphatic diol compound selected from ethylene glycol, butane diol, and/or cyclohexanedimethanol, where the solid dispersion of anhydrosugar alcohol is obtained by introducing a nanomaterial into an anhydrosugar alcohol in an aqueous dispersion state.
