The preparation and characterization of some polymeric Schiff base‐metal complexes based on thermo‐responsive copolymer composed of N‐isopropylacrylamide and acrylamide (poly (NIPAM‐co‐AAM)) is explained. Poly (NIPAM‐co‐AAM) was produced via conventional radical polymerization method with phase transition around 35 °C. The copolymer was amino modified followed by reaction with different aldehydes to produce polymeric Schiff‐bases and utilized as an absorbent for heavy metals. The polymeric complexes were used in the role of catalyst for hydrogen peroxide decomposition as a sample reaction. The significant characteristic of these thermo‐responsive copolymers is facilitating the catalyst recovery from the reaction components by heating above the lower critical solution temperature (LCST). The effect of different parameters such as ligand and metal ion type and reaction temperature was explored on the activity of these polymeric metal catalysts.
