Abstract: A polyester resin composition containing a polyester resin, and a fine cellulose fiber composite having an average fiber diameter of from 0.1 to 200 nm, wherein the fine cellulose fiber composite contains fine cellulose fibers and hydrocarbon groups being connected thereto via an amide bond. The polyester resin composition of the present invention can be worked into a molded article by thermoforming or injection-molding, and is suitably used for various industrial applications, such as daily sundries, household electric appliance parts, packaging materials for household electric appliance parts, and automobile parts. In addition, the fine cellulose fiber composite has high dispersibility against various resins and can exhibit thickening effects, so that it is suitable as various thickeners or the like.

Abstract: PROBLEM TO BE SOLVED: To provide a surface-modified cellulose microfiber that has a high dispersibility regardless of the polarity of a solvent and is capable of developing a thickening effect.SOLUTION: A method for producing a surface-modified cellulose microfiber includes the steps of: oxidizing a natural cellulose fiber in the presence of a N-oxyl compound to obtain a cellulose microfiber containing a carboxyl group; and reacting the cellulose microfiber containing a carboxyl group with a primary or secondary amine having a 1-4C hydrocarbon group. The surface-modified cellulose microfiber has an average fiber diameter of 0.5-200 nm and is obtained by linking a 1-4C hydrocarbon group through an amide bond.
