CA 2733501
A film-forming polymer with improved chemical stability in antifouling coating applications, said polymer bearing pendant to its backbone a salt of (i) a basic group with a first pKa of the conjugate acid of at least 4.0 and (ii) an organic acid with a first pKa of 2.0 or less; said basic group being covalently bonded to the polymer backbone.
La présente invention concerne un polymère filmogène ayant une stabilité chimique améliorée dans des applications de revêtement antifouling, ledit polymère portant dans le groupe latéral de son squelette un sel (i) dun groupe basique avec un premier pKa de lacide conjugué dau moins 4,0 et (ii) dun acide organique ayant un premier pKa de 2,0 ou moins, ledit groupe basique étant lié de manière covalente au squelette polymère.
