Document Type and Number:
WIPO Patent Application WO/2021/172407
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a resin composition having excellent strength and ductility and containing hydrophobic cellulose fibers; a method for producing the same; and a molded body. The present invention relates to a fiber-reinforced resin composition (D) containing microfibrillated hydrophobic cellulose-based fibers (A), a fibrillation agent (B1), and a thermoplastic resin (C), wherein the microfibrillated hydrophobic cellulose-based fibers (A) are modified by an acyl group having 2-5 carbons, and the fibrillation agent (B1) is at least one compound selected from the group consisting of polyalcohol having a molecular weight of 130 to 400 and lactone having a molecular weight of 86 to 115.
