The decarboxylation of N-oxyphthalimide-based polyolefin-precursor polymers, copolymers and block copolymers is suitable for radical based post-polymerization modifications. The removal of the N-oxyphthalimide side group on the one hand gives the opportunity to develop a new and innovative method for the synthesis of well-defined polyolefin-like structures and on the other hand allows for the introduction of new functional groups to a polymeric system, realized by thermally- or photo-induced decarboxylation reactions based on transition metal redox catalysis.
