Poly-1, poly-3 and poly-4 were tested for their ability to bind to Cu(II). Poly-3 was of particular interest due to its carboxylic acid functional groups. Carboxylates are commonly used donor sites for coordination with metals such as copper and ionic polymers can have improved water solubility which may improve metal binding in aqueous solutions. Therefore, poly-3 was reacted with 1 molar equivalent of NaOH per carboxylic acid group to provide the watersoluble Na poly-3 (S90-S91).
