Patent ID: 8846817

Claim:
A polymer comprising units of formula VI wherein each b=0 or 1; each X is independently a hydrogen, 1/z of a metal ion of charge z, a protonated nitrogen base, or a tetrasubstituted organic ammonium compound; the molar ratio of q:r:s:t=(99.99-0.1):(0-99.9):(0-98):(0-30), wherein s+t is at least 1; R 1 , R 2 , and R 3 are each independently a hydrogen or C 1-4 alkyl; R 4 , R 5 , R 6 and R 7 are each independently a hydrogen, C 1-4 alkyl or F, wherein F is a functional group that imparts a property to the polymer VI, at least one and no more than two of R 4 , R 5 , R 6 and R 7 are F and F is the same or different in each instance; G is a single bond or a C 1-30 hydrocarbyl group; and for each instance of t when t is not zero, c=0-5 and d=0-5, provided that c+d=1-5, and wherein q, r and s as present in c are independent of any other value of q, r and s.
