1. A method for making a water-dispersible or water-dispersed polymer, comprising the steps of:
a) reacting (i) an unsaturated monomer containing one or more cyclic carbonate groups, or (ii) an unsaturated or saturated oligomer or polymer containing a plurality of cyclic carbonate groups, with a tertiary amine in the presence of an acid, or with an acid in the presence of a tertiary amine, or in the presence of an acid and a tertiary amine, to provide a water-dispersible or water-dispersed monomer, oligomer or polymer; and
b1) when step a) provides a water-dispersible or water-dispersed monomer or oligomer, reacting such monomer or oligomer with one or more monomers in the presence of an initiator to provide a water-dispersible or water-dispersed polymer; and
b2) when step a) provides a water-dispersible or water-dispersed polymer, optionally using such polymer to support emulsion polymerization of one or more unsaturated monomers in the presence of an initiator to provide a water-dispersible or water-dispersed further polymer
wherein step a), step b1) or step b2) provides a latex polymer formed using a polymeric surfactant, and the unsaturated monomer containing one or more cyclic carbonate groups and one or more other unsaturated monomers are emulsion polymerized in the presence of the polymeric surfactant.
