Amine-containing polymers, dispersions thereof and methods of making and using the same

An aqueous dispersion comprising a fluorinated polymer comprising:

• (a) an aqueous continuous phase;
• and
• (b) a plurality of fluorinated polymer particles, wherein the fluorinated polymer particle comprises interpolymerized units of (i) a fluorinated terminal alkene monomer and (ii) a tertiary amine-containing fluorinated monomer wherein the tertiary amine-containing fluorinated monomer is selected from at least one of the following formulas:
• where X1 is selected from H, F, or CF3;
• X2 is selected from H or F;
• X3 is selected from H, F, or a C1-C4 alkyl or a C1-C4 fluoroalkyl, wherein at least one of X1, X2 or X3 is not H or F;
• and
• each Rf group are (i) independently selected from a linear or branched perfluorinated alkyl group comprising 1 to 8 carbon atoms and optionally comprising at least one catenated O or N atom;
• or (ii) bonded together to form a ring structure comprising 4 to 8 carbon atoms and optionally comprising at least one catenated O or N atom;
• or
• where X1, X2, and X3 are independently selected from H, F, or CF3;
• Y1 is H or F;
• Y2 is F or CF3;
• wherein at least one of X1, X2, or X3 is CF3;
• and
• each Rf group are (i) independently selected from a linear or branched perfluorinated alkyl group comprising 1 to 8 carbon atoms and optionally comprising at least one catenated O or N atom;
• or (ii) bonded together to form a ring structure comprising 4 to 8 carbon atoms and optionally comprising at least one catenated O or N atom.
