A polymeric chelating agent comprising a carbon polymer backbone and the method of use are described. The polymeric chelating agent of formula I wherein each R is the same or different and each Ra is the same or different, wherein R and Ra are each independently H, C1-20alkyl, C2-20alkenyl, C2-20alkynyl, C5-20aryl, C1-20heteroalkyl, C2-20heteroalkenyl, C2-20heteroalkynyl, or C5-20heteroaryl, wherein the C1-20heteroalkyl, the C2-20heteroalkenyl and the C2-20heteroalkynyl, and the C5-20heteroaryl each comprise one or more N, S, or O groups, n is integer from 0 to 16, n1 is a integer, and relates to the total molecular weight of the polymeric chelating agent, R1, R2, R3, R4 to R n1 are the same or different and are each independently H, C1-100alkyl, C2-100alkenyl, C2-100alkynyl, or C1-100alkylaryl each substituted or unsubstituted wherein if R1, R2, R3, R4 to R n1 comprise a substituent each substituent is R, or salt thereof. |
