ABSTRACT:
A facile process for converting polyketones to polyesters is provided. The process involves reacting a polyketone, such as an ethylene-carbon monoxide copolymer, with an organic peroxyacid oxidizing agent in an inert liquid medium at a temperature from -20.degree. C. to 150.degree. C. to convert substantially all or only a portion of the keto functionality to ester moieties.
