摘要：
A hydrophilic vinylidene fluoride resin composition, comprising: porous vinylidene fluoride polymer particles and a hydrophilic polymer having a weight-average molecular weight of at least 2×105 contained in the pores of the porous vinylidene fluoride polymer particles. The composition is preferably obtained by subjecting a slurry containing porous vinylidene fluoride polymer particles after suspension polymerization to an appropriate degree of heat treatment for adjusting the amount of residual polymerization initiator, then impregnating the Polymer particles with a hydrophilic monomer and polymerizing the monomer. The thus-obtained vinylidene fluoride resin composition exhibits persistent hydrophilicity and good processability.
