摘要：The crosslinked copolymer containing 75 to 99.9% by weight of recurring unitsof a pyridyl, quinolyl, isoquinolyl or pyrazinyl compound containing a polymerizableolefinic group, 0.1 to 25% by weight of units of a crosslinking agent and 0 to 25% by aweight of units of a polymerizable organosilicon and/or organoboron compound and,based on 100% by weight of the sum of the abovementioned units, 5 to 350% by weightof units of an N-vinyl-amide, is prepared by bead polymerization and used as a sorbentfor acid substances from their aqueous solutions.
