摘要： A process for removing aluminum ions from beer or juice, in which the beer or fruit juice is contacted with from 5 to 2500 g per 100 l of a polymer which contains, as copolymerized units, from 50 to 99.5% by weight of at least one basic vinyl heterocycle having a pK.sub.a of at least 3.8 and from 0 to 49.5% by weight of another copolymerizable monomer, and which was prepared in the absence of oxygen and polymerization initiators and in the presence of from 0.5 to 10% by weight, based on the monomers, of a crosslinker.
