Kinetics of the Non-Catalysed Hydrolysis of Vinyl Acetate in an Aqueous Medium

Interfacial complexation of a neutral amphiphilic ‘tardigrade’ co-polymer with a cationic surfactant: Transition from synergy to competition

“…This γ behaviour suggests that, at 0.5 cmc DTAB, there was a strong interaction between the polymer and surfactant in the bulk, suppressing the formation of a monolayer of either component with no additional synergistic adsorption observed. The carbonyl (ester) groups in the PVAc side chains could partially hydrolyse, resulting in negatively charged OHgroups in the polymer structure [48,49], providing additional attractive electrostatic interactions between the PEG-g-PVAc and the cationic DTAB.…”

“…The positive DTAB headgroup would interact with negatively charged species, such as OHgroups from partially dissociated PVAc grafts [48,49] via attractive electrostatic forces.…”
