摘要：
Poly (acryloyl benzoic hydrazide) and its complexes with some transition metals were prepared and characterized by elemental analysis, IR, UV-vis spectra and magnetic measurements. The results showed that the homopolymer reacted with Fe(III) chloride and Zn(II) acetate in 1:1 and with Co(II), Ni(II) and Cu(II) chlorides in 1:2 (metal: ligand) molar ratio. Thermal analysis measurements showed that the thermal stabilities of the polymer complexes are higher than the homopolymer which is attributed to the formation of stable 5-membered chelate ring. Electrical measurements indicated that the homopolymer and its corresponding metal complexes are within the insulator range. (C) 2000 Published by Elsevier Science Ltd. All rights reserved.
