A polymer comprising a polymer chain having at least one fused aromatic imide pendant group, wherein the polymer is represented by formula: wherein each variable is independently R 1 is a substituent on Q ring in any position available for bonding to a substituent group and R 1 is represented by one or more of -an electron withdrawing group chosen from a halogen, a nitrile, a carbonyl group, a nitro group, a sulphamoyl group, a sulphonate group, a hydroxy group, a carboxyl group, or an amino group; a is 0, 1 or 2; R 2 is a C 1 to C 20 hydrocarbylene group or a C 1 to C 20 hydrocarbonylene group when R 2 contains more than 2 carbon atoms, the hydrocarbylene group or hydrocarbonylene group is linear or branched or mixtures thereof; R 3 is a H or C 1-50 -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 C 1-50 -hydrocarbonyl group (i.e., a hydrocarbyl group containing a carbonyl 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; Pol is a homopolymer chain or a copolymer chain, wherein the polymer chain is selected from the group consisting essentially of a Poly(ether), Poly(ester), Poly(ester amide), Poly(amide), Poly(alkylene), and mixtures thereof; u is 1 to 3; v is 1 to 2; w is 1 to 3; v is 2 when W is Nitrogen; v is 1 when W is Oxygen, Sulphur, >NG; G is a hydrogen or a hydrocarbyl group containing 1 to 200, or 1 to 100, or 1 to 30 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 (typically 6 membered).
