The accounts of the resin swing aperfeicoadas ions, process for preparing the accounts of copolimero hard, cross-linked, individualized, and process for producing a resin swing ions

摘要

P the invention relates to the preparation of the beads of resins copolymers. / p & & p & the copolymerization is effected by a mixture of monoethylenically unsaturated by free radicals, in aqueous suspension, and an unsaturated monomer polyethylenically as crosslinking agent in a proportion of less than 50% by weight, and which has at least two ethylenically unsaturated reactive radicals, the reaction being carried out in the presence of oxygen or by contact with, or dissolved in the monomer mixture. / p & & p & the pearls thus obtained, after fixing of the radicals can be used as ion exchangers, and have the physical characteristics are improved. / p
