Abstract: Iodine complexes can be prepared of water-insoluble but water swellable cross-linked N-vinyllactam or N-alkyl-N-vinylamide polymers in the form of porous beads or granules. Such complexes are suitable as bactericide and water treatment aids in gravity filtration systems or packed columns, such aids having the advantage of rapid throughput. The complexes are prepared by reacting the cross-linked particulate polymeric material with elemental iodine either by a dry blending or iodine and polymer solids or by mixing of the porous polymer with a solution of iodine.

Abstract translation: 碘络合物可以以多孔珠或颗粒的形式制备不溶于水的水溶胀交联的N-乙烯基内酰胺或N-烷基-N-乙烯基酰胺聚合物。 这种络合物适合作为重力过滤系统或填料塔中的杀菌剂和水处理助剂，这种助剂具有快速生产的优点。 通过使干交联或碘和聚合物固体或通过将多孔聚合物与碘溶液混合，使交联的颗粒状聚合物与元素碘反应来制备络合物。
