SYNTHESIS CHARACTERIZATION and CATALYTIC ACTIVITY STUDIES OF POLYMER SUPPORTED SCHIFF BASE METAL COMPLEXES

Abstract

The literature review has clearly demonstrated that various metal ions have been immobilized on polymer supports, which either have enhanced the activity of the catalysts or helped in improving the extent of reaction. Catalyst system comprising a polymer support in which catalytically active species are immobilized through chemical bonds or weaker interactions such as hydrogen bonds or donor acceptor interactions. Polymer-supported catalysts are often based on network polymers in the form of beads. They are easy to separate from reaction media and can be used repeatedly. Examples of polymer-supported catalysts are: (a) a polymer metal complex that can coordinate reactants, (b) colloidal palladium dispersed in a swollen network polymer that can act as a hydrogenation catalyst. Polymer-supported enzymes are a type of polymer-supported catalysts. Currently the major efforts in academic research and industry are directed to the development of environmentally friendly synthetic procedures. Using polymer-supported catalysts offers a great advantage over traditional methods, science it avoids contamination with toxic transition metal newline
