Abstract
The synthesis of polyethylene glycol)-based surface active agents was undertaken via copper mediated living radical polymrisation.
In a first approach, polyethylene glycol) was used as macroinitiator for the synthesis of polyethylene glycol) methyl ether-b-poly(methyl methacrylate) (MeOPEG-b- PMMA) block copolymers. The living character of the polymerisation was demonstrated, but MeOPEG was found to be a slow initiator.
In a second approach, MeOPEG was used as a methacrylate macromonomer (MeOPEG-MA). Graft polymers were obtained by polymerisation in toluene and water, and various block copolymers, aiming to increase the hydrophobicity character of the final molecules, were also synthesised.
The kinetics of the polymerisation was then studied, and various oxygen containing molecules were found to influence the polymerisation by polarity effect on the solution and potential competitive coordination with the ligands on the copper catalyst.
Finally, the physical properties of the block and graft copolymers synthesised were tested. Thermal analyses, surface properties of the PMMA block copolymers and aggregates formation in aqueous solution were investigated.
