Patent ID: 10858485

Abstract:
An object of the present invention is to provide a highly versatile master batch for producing a fiber-reinforced resin composition with high strength even when a highly hydrophobic resin is used as a resin for dilution (a resin that constitutes a fiber-reinforced resin composition). The master batch contains AcylMFs (A), a Pm (B), and a Com (C) and is for use in the production of a fiber-reinforced resin composition by mixing with a Pd (D), wherein the AcylMFs (A), Pm (B), Com (C), and Pd (D) satisfy the following conditions: (a) the AcylMFs (A) have an SPacylmf of 10 or more; (b) the Pm (B) has an SPpm of 9 to 15, and the SPpm is equal to or greater than the SPpd of the Pd (D); and (c) the Com (C) has an SPcom equal to or less than the SPacylmf of the AcylMFs (A).
