METHOD FOR PRODUCING RESIN COMPOSITION COMPRISING MODIFIED MICROFIBRILLATED PLANT FIBERS, AND SAME RESIN COMPOSITION

WIPO Patent Application WO/2013/133093

A1

Provided is a method for producing a resin composition with which, by means of simple steps, microfibrillated plant fibers can be uniformly dispersed in a highly hydrophobic resin and mechanical strength of the molded material obtained by molding the resulting resin composition can be improved. Moreover, provided is a resin composition having excellent heat resistance and low linear thermal expansion. The present invention relates to a method for producing a resin composition comprising a step for mixing, in the presence of an organic liquid (C), a thermoplastic resin or thermosetting resin (A), and modified plant fibers (b) or modified microfibrillated plant fibers (B) obtained by modification with an alkyl or alkenyl succinic anhydride in a liquid capable of swelling microfibrillated plant fibers (B') or plant fibers (b).
