<p>Terpolymers comprising (i) from 55 to 80 percent by weight of units derived from a perfluoroaliphatic acrylate or methacrylate monomer, (ii) from 15 to 35 percent by weight of units derived from a nonfluorinated polyethylene oxide acrylate or methacrylate monomer, and (iii) from 1 to 15 percent by weight of units derived from a nonfluorinated dialkylaminoethyl acrylate or methacrylate monomer in its free base, amine salt, quaternary ammonium, or amine oxide form. The terpolymers are useful in oil and water repellency applications.</p> |
