A B S T R A C T COMPLEX-FORMING POLYMERS Novel complex-forming polymers are provided having at least one aryl group carrying a complex-forming moiety of general formula Image which can be prepared by contacting a compound of general formula IV Image with a metalating agent, followed by reaction of the metalated compound with either A.1. at least one vinylbenzyl halide, and subsequently 2. polymerizing the reaction product of A.1. or B. a halomethylated polystyrene polymer; wherein each R individually is H, or both R's together form a group -CH-CH-; R1 is H or an alkyl, R2 is H, an alkyl, a vinylbenzyl group or a group Image R1 and R2 together form a group -(CH2)n- wherein n is an integer in the range of from 2 up to and including 6; R is an alkyl, alkoxy, phenyl, phenoxy, alkylthio or phenylthio group; R4 is an alkyl group, or a cycloaliphatic group having from 3 to 7 carbon atoms having at least one hydrogen on the .alpha.-carbon atom; p and q are integers from O up to and including 2 and from O up to and including 3, respectively; -CR1(R2)-CH2- and/or R4 are linked to a carbon atom which occupies the ortho- or para-position with respect to the nitrogen atom in the heterocyclic aromatic ring. The products are hydrolytically stable and may be used e.g. as polymeric ligands, as such, or e.g. complexed with selected metal compounds.
