Three novel polymers incorporating Schiff bases

derived from condensation reactions of poly(acrylamide) with 5-chloro-2-hydroxybenzaldehyde

5-bromo-2-hydroxybenzaldehyde and 5-methyl-2-hydroxybenzaldehyde

have been synthesized

and their Cu(II) and Ni(II) complexes have been prepared. The 1H-NMR signals of the ―CH＝N― and ―NH2 groups have been utilized to determine the relative abundances of Schiff base and acrylamide groups in the polymers containing Schiff bases. Poly(acrylamide) incorporating Schiff bases and metal complexes thereof have been characterized by molar conductance

magnetic susceptibility and electronic and IR spectral studies. The selectivity of poly(acrylamide) incorporating Schiff bases in forming Ni(II)-aldehyde and Cu(II)-aldehyde complexes has been studied. The Cu(II) and Ni(II) contents in the metal-bearing polymer complexes were determined by the ICP-MS technique.
