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 SPof 10 or more; (b) the Pm (B) has an SPof 9 to 15, and the SPis equal to or greater than the SPof the Pd (D); and (c) the Com (C) has an SPequal to or less than the SPof the AcylMFs (A).

Master batch containing acylation-modified microfibrillated plant fibers

The present invention provides a method for producing a resin composition, which, by means of simple steps, can uniformly disperse microfibrillated plant fiber in a highly hydrophobic resin and can impart enhanced mechanical strength to a molding material obtained by molding the resin composition. The present invention further provides a resin composition having excellent heat resistance and low linear thermal expansion. The present invention relates to a method for producing a resin composition, the method including a step of mixing a thermoplastic resin or thermosetting resin (A), and modified plant fiber (b) or modified microfibrillated plant fiber (B), in the presence of an organic liquid (C), the modified plant fiber (b) or modified microfibrillated plant fiber (B) being obtained by modification with an alkyl or alkenyl succinic anhydride in a liquid capable of swelling microfibrillated plant fiber (B') or plant fiber (b).
