Abstract
An amphiphilic polymer comprising: at least 10 wt-% monomeric units comprising alkylene oxide moieties, wherein a majority of the alkylene oxide moieties are ethylene oxide moieties; monomeric units comprising hexafluoropropylene oxide oligomeric moieties having the formula C3F7O—(CF(CF3)CF2O)aCF(CF3)—C(O)N(H)-Q-, wherein Q is a linking group with at least one carbon atom, and “a” is at least 5; and monomeric units comprising pendant groups selected from phosphate groups, phosphonate groups, sulfonate groups, and combinations thereof; wherein the amphiphilic polymer is water dispersible; aqueous coating compositions containing the amphiphilic polymer; and methods of treating a hard surface.
