Abstract
The invention is a complex-forming polymer comprising at least one aryl group having a 2,2'-bipyridine complex-forming moiety or a 1,10-phenanthroline complex-forming moiety. The complex-forming polymers are prepared by contacting a substituted 2,2'-bipyridine or a substituted 1,10-phenanthroline compound with a metalating agent, and then reacting the metalated compound with an halomethylated polystyrene polymer, or alternatively, reacting the metalated compound with at least one vinylbenzyl halide and subsequently polymerizing the reaction product. The complex-forming polymers are hydrolytically stable and may be used as polymeric ligands as such or complexed with selected metal compounds.
