Abstract: Water-dispersible or water-dispersed polymers are made by 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. When step a) provides a monomer or oligomer, the monomer or oligomer is reacted with one or more monomers in the presence of an initiator to provide a water-dispersible or water-dispersed polymer. When step a) provides a polymer, the polymer is optionally used 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.

Abstract: An aqueous dispersion comprising: water; a hydrophobic aromatic polyester having a number average molecular weight of greater than 7,000 Daltons; and a water-dispersible aromatic polyester dispersant; wherein the hydrophobic aromatic polyester and the water-dispersible aromatic polyester dispersant form a stable aqueous dispersion; and wherein the hydrophobic aromatic polyester is present in the aqueous dispersion in an amount of less than 50 wt-%, based on the total weight of the hydrophobic aromatic polyester and the water-dispersible aromatic polyester dispersant.
