SILYL TERMINATED SULFOPOLY(ESTER-URETHANE) COMPOSITIONS

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 equ...

Beschreibung
Zusammenfassung:	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. Compositions de sulfopolyester-uréthane pouvant se disperser dans l'eau et dont le squelette comprend au moins un groupe acide sulfonique d'arylène ou d'alkylène, ou un de ses sels, le polymère étant terminé par au moins un groupe silyle hydrolysable. Ces compositions présentent, de préférence, un poids équivalent de sulfonate de 500 à 12 000 g/équivalent et un poids moléculaire moyen inférieur à 50 000. Ces compositions sont utiles pour effectuer des traitements durables, par exemple pour former des revêtements de surface à basse énergie présentant une caractéristique de non adhérence vis-à-vis des matériaux adhésifs, de la graisse et de l'huile.
