Patent ID: 8614275

Claim:
A polymer prepared from reactants comprising: a) a first monomer having the structure of Formula I b) a second monomer having the structure of Formula II c) a third monomer having the structure of Formula III and d) a quaternizing agent selected from at least one of formic acid, acetic acid, and propionic acid, wherein R f is selected from a structure of Formula IV, Formula V, and combinations thereof F(C m F 2m O) n C p F 2p —, (IV) C x F 2x+1 SO 2 N(R 1 )—, (V) wherein A is a linking group having less than 11 carbon atoms; m is an integer of 1 to 12; n is an integer of 1 to 40; p is an integer of 1 to 6; x is an integer of 1 to 6; R 1 is selected from a hydrogen atom, an alkyl group, an aryl group, and an aralkyl group, and combinations thereof; R 6 , R 8 , and R 11 are independently a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; R 2 comprises at least one of an alkylene group, a heteroalkylene group, an arylene group, or an aralkylene group; each R 3 is independently a hydrogen atom or an alkyl group; R 4 comprises 1 to 10 carbon atoms; and each R 5 is independently a hydroxy group, an alkoxy group, an acyl group, an acyloxy group, a halo group, an ether group, and a polyether group; wherein the polymer is substantially free of amino groups.
