ABSTRACT:
Disclosed is a water-dissipatable or dispersible polyester containing sulfonate groups that has improved stability having a substantial number of capped carboxyl groups attached to the sulfomonomer moieties. This polyester can be prepared by capping the carboxyl end groups of the polyester with oxirane compounds or by polymerizing the reactants wherein one reactant is a diol that is a diester adduct of a glycol and a dicarboxylic acid sulfomonomer.
