Abstract: Processes for converting vinyl alcohol polymers to poly(keto-esters) and the novel products obtained therefrom are disclosed. The process involves reacting a vinyl alcohol polymer, such as PVA or EVOH, with an organic peroxyacid oxidizing agent in an inert liquid medium at a temperature from -20.degree. C. to 150.degree.

In another aspect of the invention, the vinyl alcohol copolymer is first reacted with an oxidizing agent capable of converting the secondary hydroxyl groups to carbonyl but not to oxycarbonyl and then subsequently oxidized using a peroxyacid to form oxycarbonyl. The poly(keto-esters) comprised of carbonyl units, oxycarbonyl units, hydroxyl-containing units and units which are primarily hydrocarbons in nature are photodegradable and biodegradable.
