ABSTRACT:
Water-dispersible sulfopoly(ester-urethane) compositions which comprise, in their backbone, at least one arylene or alkylene sulfonic acid group or a salt thereof, the polymer being terminated by at least one hydrolyzable silyl group. The compositions of the invention preferably have a sulfonate equivalent weight of about 500 to about 12,000 g/equivalent and a number average molecular weight less than 50,000. Compositions of the invention have utility as durable treatments such as low surface energy coatings that exhibit release towards adhesive materials, grease, and oils.
