More Information
Summary:The invention relates to a polymer comprising structural units of formula and formula wherein R1, R2, R5 and R6 are independently hydrogen, a methyl group, or -COOH, only one of R1 and R2 or R5 and R6 is -COOH; R3 and R7 are independently hydrogen, or a methyl group; R4 is -COOH, -CONH2 or -OH, when R4 is -OH, R1, R2 and R3 are respectively hydrogen; and R8 is -COO, -CONH, or -O-, when R8 is -O-, R5, R6 and R7 are respectively hydrogen. Methods for preparing and using the polymer are also described herein.
