Poly(NIPAM-co-4-VP) undergoes a phase transition at the low critical solution temperature with a change from the hydrophilic to the hydrophobic core in a hydrophilic solvent. Palladium nanoparticles supported on such a thermoresponsive polymer support were demonstrated to catalyze the Tsuji-Trost reaction for the arylation of various cinnamyl carbonates by arylboronic acids. Therefore, a protocol developed using mild reaction conditions demonstrates the recyclability of the catalyst in an eco-friendly solvent such as water.

See Results and discussionPolymer behaviour and morphology According to differential scanning calorimetry (DSC) studies, the polymer coils around itself and results in behavioural changes from the hydrophilic to hydrophobic polymer core in a hydrophilic solvent like water.
