PROBLEM TO BE SOLVED: To improve tensile strength, elongation at break, and tensile strength at break and improve toughness (toughness) by adding CNF dry body to a resin body at a low filling amount of 5% by mass or less and mixing it. The resin composition is provided. In a resin composition comprising (A) a CNF dried product prepared from cellulose nanofiber (CNF), (B) an acid-modified polypropylene, and (C) a polyolefin resin, the CNF dried product comprises: CNF obtained by causing the cellulose dispersion fluid to collide with the collision hard bodies or to collide with each other through a high pressure injection treatment of 100 to 245 MPa through a nozzle having a diameter of 0.1 to 0.8 mm, It is a dry body of CNF obtained by drying, and the mass ratio of the CNF dry body: the acid-modified polypropylene: the polyolefin resin = 0.01 to 5: 0.01 to 10:85 to 99.8. A resin composition to be mixed. [Selection] Figure 3 |
