Abrégé
The instant invention relates to thionolactone compounds useful as comonomers to introduce weak bonds for polymer degradation or functionalization. The invention is also directed to processes for the preparation of said compounds, notably by thionation of the corresponding lactones. The invention is furthermore directed to uses of said thionolactones as comonomers, copolymers made from these comonomers, and processes for the preparation of said copolymers.
