Synthesis of New Glycine-based Polymers and their Thermoresponsive Behavior in Water

Résumé

In this work, we develop new glycine‐derived polymers that exhibit thermoresponsive properties in water. Therefore, a series of monomers containing one, two or three amide functional groups and one terminal cyanomethyl group is synthesized. The resulting homopolymers, obtained by free radical polymerization (FRP) and reversible addition fragmentation chain transfer (RAFT) polymerization, display a sharp and reversible upper critical solution temperature (UCST)‐type phase transition in water. Additionally, we show that the cloud point can be adjusted over more than 60 °C by the number of glycyl groups present in the monomer structure and by the polymer's molar mass. These novel thermoresponsive polymers based on cyanomethylglycinamide enrich the range of non‐ionic UCST polymers and are promising to find applications in various fields.
