摘要：
A method for producing an aqueous absorptive polymer-containing resin composition in which a resin composition is doped with an aqueous absorptive polymer includes causing the aqueous absorptive polymer to absorb and be swollen by water beforehand, and milling and microparticulating the water-absorbed and -swollen absorptive polymer at an ultrasonic flow pressure of not less than 50 MPa.
