Some polyvinyl pyrrolidone–metal complexes (abbreviated as PVP‐M) have been prepared by the reaction of polyvinyl pyrrolidone with metal acetate, and have been characterized by its performance toward the polycondensation of glutaric acid and glycols to produce polyester oligomers under mild conditions. The molecular weight of the oligomers was influenced by the type of metal, the molar ratio of two metals (M 1 /M 2 ), the molar ratio of the ligand atom to metal (N/M) in the complex, and the kind of glycol used in the reaction.
