The evidences presented here indicate that water-phase polymerisation controls the kinetics of microemulsion copolymerisation. However, a more thorough and systematic study of the role of the monomer solubility is needed to understand the di?erences in the kinetic behaviour between water-insoluble, partly water-soluble and water-soluble monomers.
