ABSTRACT:
Disclosed is a process for producing water-dispersible polymers, particularly condensation polymers such as polyesters, polyethers and polyamides, by forming an ethylenically unsaturated polymeric precursor by condensation polymerization of reactants including ethylenically unsaturated reactants and then sulfonating the ethylenic unsaturation of said polymeric precursor by reacting it with a sulfonating agent such as bisulfite, metabisulfite, or a mixture thereof.
