Grafting and studying of some biological properties of chitin

İn this work, crystal chitin grafted with some monomers by Atom Transfer Radical Polymerization method. İn this technic primer ?OH groups of chitin reacted with chloroacetylchloride. Then chitinchloroacetate was grafted with methachrilamide (MAM), diacetonacrylamide (DAAM), 4-nitrophenylacrylamide (NFAA), 2-hydroxiethylmethachrilate (HEMA) chitin using chloracetyl group as macroinitiator and CuCl / 2,2?-bipyridine as catalyzor system.Graft copolymers chracterized by elemental analysis and IR methods. Thermal stability and thermal transition of whole copolymers studied by thermogravimetric analysis (TGA) method.İn addition, graft copolymers, such as free-radical reduction activities and the biological activity of antitumor activity by examining the results were evaluated.As a result, copolymers in the IR, elemental and thermal analysis and the results of biological activity results were fitted to the data of literatüre.
