Abstract Poly(4-vinylpyridine) was crosslinked with 1,4-dibromobutane, The obtained resin (DBQP) formed a stable complex with Cu2+, and the adsorption capacity of DBQP varied with the degree of crosslinking. The complex, formation of DBQP with Cu2+ was studied by examining the adsorption equilibrium and the spectroscopic measurement. The resin complex seems to be formed via no step-by-step mechanism, and the stability constant was appreciably large in comparison with those of non-crosslinked polymers and of a monomeric analogue. In the highfy crosslinked resins, the ligand-field is relatively weak and the stability of the Cu2+ complex is decreased.
