Title:
POROUS GRAFT COPOLYMER PARTICLES, METHOD FOR PRODUCING SAME, AND ADSORBENT MATERIAL USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/069474
Kind Code:
A1
Abstract:
Provided are: a graft copolymer which enables a large amount of introduction of an adsorptive functional group that adsorbs a metal and the like; a method for producing this graft copolymer; and an adsorbent material which uses this graft copolymer. (1) Porous graft copolymer particles which are obtained by introducing graft chains into porous particles (having pores that have an average pore diameter of 0.01-50 μm on the particle surfaces) which are formed of a resin (polymer (A)) that is selected from the group consisting of an olefin resin, a water-insoluble modified vinyl alcohol resin, an amide resin, a cellulose resin, a chitosan resin and a (meth)acrylic acid ester resin. (2) A method for producing porous graft copolymer particles, which comprises: a step (I) for obtaining a composite body by melting and mixing the polymer (A) and a polymer (B) that is different from the polymer (A); a step (II) for obtaining a porous body that is formed of the polymer (A) by extracting the polymer (B) from the composite body; a step (III) for pulverizing the porous body; and a step (IV) for introducing graft chains into particles of the porous body. (3) An adsorbent material which is formed of the porous graft copolymer particles.
