Thermal stability of polymer complexes of acryloyl-p-chlorobenzoic hydrazide with some transition metal chlorides and acetates

摘要

Poly (acryloyl-p-chlorobenzoic hydrazide) and its complexes with some transition metal chlorides and acetates were prepared and characterized by elemental analysis, electronic and vibration spectroscopy and magnetic measurements. Poly (acryloyl-p-chlor- obenzoic hydrazide) reacted with Fe(III), Co(II) and Cu(II) chlorides and Co(II), Cu(II) and Zn(II) acetates in 1:1 (metal:ligand) molar ratio, and with Ni(II) chloride in 1:2, but with Ni(II) acetate in 2:1 (metal:ligand) molar ratio. The thermal stability was investigated using thermogravimetric analysis. The results showed that the polymer complexes are more stable than the homopolymer.
