2‐Hydroxy‐4‐acryloyloxybenzophenone (HABP), prepared from acryloyl chloride with 2,4‐dihydroxybenzophenone, was polymerized in methyl ethyl ketone at 70°C using benzoyl peroxide as initiator. Polychelates were obtained in the dimethylformamide solution of poly(HABP) containing a few drops of ammonia with the aqueous solution of Cu(II)/Ni(II) ions. The polymer and polychelates were characterized by elemental analyses and spectral studies. Elemental analyses of the polychelates suggest a metal to ligand ratio of 1:2. The IR spectral data of polychelates indicate that the metals were coordinated through the oxygen of the keto group and the oxygen of the phenolic‐OH group. The diffuse reflectance spectra, electron paramagnetic resonance, and magnetic moments of the polychelates show an octahedral and square planar structure for poly(HABP)‐Ni(II) and poly(HABP)‐Cu(II) complexes, respectively. X‐ray diffraction studies revealed a high crystalline nature of the polychelates. The thermal properties of polymer and metal complexes and their catalytic activity are discussed. © 1996 John Wiley & Sons, Inc.
