Abstract

A process for the preparation of polycarbonylic compounds, characterized in that unsaturated olefinic copolymers, containing unsaturations in side groups or cyclic groups belonging to the main chain, are oxidized by means of gaseous mixtures containing oxygen and/or ozone and/or by means of substances to release oxygen, the operating conditions being chosen so that only the formation of carbonyl groups is reached in correspondence with at least part of the unsaturations present in said copolymers.
