Abstract

A process for converting the pendant keto groups of ketonic polymers to ester groups is provided. The process involves reacting the polymer with an organic peroxyacid oxodizing 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 pendant carbonyl functionality to oxycarbonyl moieties. Homopolymers or copolymers of .alpha., .beta.-unsaturated ketones, such as methyl vinyl ketone and ethyl vinyl ketone, are readily modified with the process of this invention.
