Vanillin was used as renewable resource for preparing new monomer in two stops. The monomer has tertiary amine group which facilitates the pH change and functional aldehyde group that encourages the formation of Schiff base. It was abbreviated by DEAMVA and evaluated using chemical analysis e.g. 1H NMR, 13C NMR and FT IR all data were in logic case. Copolymerization of Styrene with 5 and 15 mol% of DEAMVA has been done by free radical polymerization and AIBN as initiator. The copolymers have been chemically and physically characterized e.g. 1H NMR, FT IR, GPC, and DSC. Post polymerization of poly (styrene-Co-DEAMVA) with 15 mol% (III b) was prepared for immobilization of tryptophan and investigated by the same methods used lately. Moreover, the sensitivity of the posted copolymer to pH has also studied by UV-vis. Spectroscopy. Scanning electron microscopy (SEM) was used to study the morphological feature of polymer surface after immobilization of tryptophan.
