SYNTHESIS AND CHARACTERIZATION OF POLYSCHIFF BASE ANILIDES AND THEIR METAL-CHELATES

2-Hydroxy-4-acryloyloxyacetophenone-N-phenylimine (HAAPI) was synthesi zed, and homo- and copolymerized with methacrylate (MA) in 2-butanone solution using 2,2'-azobisisobutyronitrile (AIBN) as initiator at 65 d egrees C. The polymers were characterized by IR and H-1 NMR spectrosco py. The percentage of HAAPI present in the copolymers was calculated b y H-1 NMR spectroscopy. The copolymerization reactivity ratios were ca lculated by the Kelen-Tudos method. The molecular weights of the polym ers were determined by gel permeation chromatography. Cu(II) and Ni(II ) chelates of the polymers were prepared. The polychelates were charac terized by IR spectroscopy, elemental analysis and conductivity measur ements. (C) 1998 Elsevier Science Ltd.
