1. A polymer comprising a polymer chain having at least one fused aromatic imide pendant group, wherein the polymer is represented by formula (1): wherein each variable is independently R1 is a substituent on Q ring in any position available for bonding to a substituent group and R1 is independently represented by at least one electron withdrawing group selected from —CN, —NO2, —SO2NR′2, SO3M, halo —NH2, or —OR′; a is 1 or 2, or 1; W is oxygen, sulphur, >NH, or >NG; R′ is independently —H, or an optionally-substituted alkyl, and the substituents is hydroxyl or halo, or mixtures thereof; R2 is a C1 to C20 hydrocarbylene group or a C1 to C20 hydrocarbonylene group, when R2 contains more than 2 carbon atoms, the hydrocarbylene group or hydrocarbonylene group is linear or branched; R3 is H or C1-50-optionally substituted hydrocarbyl group that bonds to a terminal oxygen atom of the polymer chain forming a terminal ether or terminal ester group and may or may not contain a group capable of polymerization such as a vinyl group, or C1-50-hydrocarbonyl group that bonds to the oxygen atom of the polymer chain forming a terminal ester group or terminal urethane group and may or may not contain a group capable of polymerization such as a vinyl group, and the substituent is halo, ether, ester, or mixtures thereof; Pol is a homopolymer chain of ethylene oxide or a copolymer chain of ethylene oxide, wherein the ethylene oxide constitutes 40 wt % to 99.99 wt % of the copolymer chain and where in the polymer chain is selected from the group consisting a poly(ether), poly(ester) and mixtures thereof; u=1 to 3; v=1 to 2; w=1 to 3 v=2 when W=>NG; v=1 when W=Oxygen, Sulphur, or >NG; G is a hydrocarbyl group containing 1 to 200 carbon atoms; and Q is a fused aromatic ring containing 4n+2 π-electrons, wherein n=2, and Q is bonded to the imide group in such a way to form a 5 or 6 membered imide ring. |
