Four coordination polymers based on the pyridyl-carboxyl ligand have been solvothermally synthesized and characterized. The heterogeneous catalytic oxidation activities of 1–3 and luminescence titration experiments for 4 have been studied.

Compositions containing polyphenylene ether-poly(alkylene dicarboxylate) copolymers are prepared by a reaction between the two polymers and, optionally, at least one functionalizing agent therefor. The functionalizing agent may first be reacted with the polyphenylene ether and the resulting functionalized polyphenylene ether in turn reacted with a functionalized or unfunctionalized poly(alkylene dicarboxylate). Alternatively, an unfunctionalized or hydroxyalkyl-functionalized polyphenylene ether may be incorporated in a conventional polyester-forming reaction. The copolymer-containing compositions are characterized by a number of desirable properties including high impact strength and solvent resistance.
