POLYOXYALKYLENE COUPLED ZWITTERIONIC MOIETY AND SURFACE ACTIVE REACTIVE POLYMERS, COATING COMPOSITIONS AND FOULING CONTROL COATINGS THEREOF

A variety of polyoxyalkylene coupled zwitterionic moieties are provided as well as surface active reactive polymers containing the polyoxyalkylene coupled zwitterionic moieties. When incorporated in coating systems, such surface active polymers show strong propensity to stratify during curing. The zwitterionic groups presented at the end of polyalkylene oxide chains can allow for effective exposure of the zwitterionic groups at the coating/water interface as the polyoxyalkylene side chains of the said SAP can further extend (to its radius of gyration) into the water phase. Additional features of the polyoxyalkylene coupled zwitterionic moieties can include a reactive end group (R) to allow covalent attachment of the moiety to a surface, a particle, a small molecule, or a polymer. Coating compositions and coated articles containing the polyoxyalkylene coupled zwitterionic moieties are also provided.
