SINTER, RESIN PARTICLES, AND PROCESS FOR PRODUCING THE SAME

摘要

Porous sintered body of polyolefin resin particles with absorbent functional groups bonded to the surface via graft polymer chains. Independent claims are also included for: (1) polyolefin resin particles in which absorbent functional groups are bonded to the surface by graft polymer chains; and (2) the manufacture of the sintered body by sintering a particle mixture of thermoplastic resin particles of diameter = 300 Microm, and crosslinked body resin particles of particle diameter = 300 Microm to which absorbent functional groups can be bonded to form a resin matrix and bonding the absorbent functional groups.
