N2 - In our ongoing research program on the development of new chelating hollow fibers based on sulfochlorinated polyethylene (PESCI), several types of chelating materials containing amine ligands were prepared by reaction of PESCI with diamines. The preparation procedure was studied carefully in the light of a possible hydrolysis reaction that can occur during the interaction of the diamine with PESCI. It was found that the reaction of PESCI with aliphatic amines differed from that with heterocyclic amines. Aminopyridines having the amine group substituted in the pyridine ring formed a sulfamide bond, which was rather unstable and could be hydrolyzed and destroyed during the reaction. However, when the NH2 group was bound to the pyridine via an aliphatic bridge, pyridine-containing chelating hollow fibers were obtained.
