Abstract
The present invention relates to a method of producing an ionomer resin particulate, comprising a step of extruding a mixture comprising a crude ionomer resin and a solvent, cooling the extruded mixture, and solidifying the crude ionomer resin in the mixture to obtain a porous particulate, wherein the crude ionomer resin comprises a (meth)acrylic acid unit (A), a neutralized (meth)acrylic acid unit (B) and an ethylene unit (C), a total amount of the unit (A) and the unit (B) is 6 to 10 mol % based on all monomeric units constituting the crude ionomer resin, and a porosity of the particulate is 60% or more.
