Abstract: 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.

Abstract: Processes to prepare aqueous polymer dispersions are provided, as well as compositions thereof, which have high solids content (e.g., 50%) with low viscosity. The process uses a selective hydrophilic macro-RAFT agent of formula (I), and is substantially free of surfactants. This process can be used to make latex polymers with good stability, which can be used widely in coatings (e.g., architectural paints, stone paints, industrial coatings, wood coatings, etc.), adhesives, sealants and mastic compositions.

Abstract: The present invention relates to the preparation of block copolymers which are particularly useful as a rheology agent, and which are suitable, inter alia, for oil extraction, which comprises a step of radical polymerization in which the following are brought into contact, in an oily medium:
monomers dissolved in the oily medium;
monomers which are insoluble in the oily medium, in the form of a micellar solution;
at least one radical polymerization initiator; and
preferably at least one radical polymerization control agent.
The invention also relates to the polymers obtained by this process and the use thereof as surfactants or dispersants.
