摘要

PROBLEM TO BE SOLVED: To provide a high performance macromolecular dispersant applicable to cellulose which is a hydrophilic substance and a practical technology for obtaining a cellulose dispersion resin composition achieving stable dispersion of cellulose when the macromolecular dispersant for cellulose is applied to cellulose and they are dispersed in a thermoplastic resin.SOLUTION: There is provided a resin composition containing a dispersant for dispersing cellulose containing a macromolecular dispersant for cellulose and a thermoplastic resin, where the macromolecular dispersant for cellulose satisfies requirement (1) to (5) and has tensile elastic modulus measured on a dumbbell piece manufactured by biaxial extrusion mixing and injection molding a mixture obtained by filtering and drying a mixture by adding 80 pts.mass of particulate high density polyethylene with condition of wetting by water to 40 pts.mass of an easily dispersible cellulose composition by treating an A-B block copolymer having a resin affinity segment A and a cellulose adsorption segment B with cellulose of 2.48 GPa or more and tensile strength of 38.9 MPa or more.SELECTED DRAWING: None
