Ion exchanger for lipoproteins separation and lipoproteins separation method using the same

摘要

An ion exchanger for lipoproteins separation, which is an ion exchanger obtained by introducing an ion exchange group into surface hydrophilic-treated porous organic polymer particles (D) prepared by subjecting the surface of porous organic polymer particles (A) to hydrophilic treatment, wherein said hydrophilic treatment is carried out by allowing the porous organic polymer particles (A) to undergo addition reaction with a compound (B) having a cyclic other group or/and a hydrophilic group and a polymerizable unsaturated double bond and then to undergo copolymerization with a polymerizable vinyl monomer (C) having a cyclic ether group or/and a hydrophilic group, and wherein the ion exchange capacity is 0.15 milliequivalent or less per 1 g of dry ion exchanger, introduced amount of the compound (B) is from 0.1 to 45% by weight based on the porous organic polymer particles (A), and copolymerized amount of the compound (C) is from 5 to 60% by weight based on the addition product obtained by allowing the porous organic polymer particles (A) to undergo addition reaction with the compound (B).
