Hydrophilic-Hydrophobic Copolymers of Functional-Ph-Responsive, and Post Polymerization

Abstract

Momen SA Abdelaty

4-hydroxy-3-methoxy benzaldehyde or Vanillin was used for preparing tertiary amine cationic monomer. The monomer has been used as pH-responsive and the functional aldehyde group was used for the formation of Schiff base. The new monomer was abbreviated by DEAMVA and investigated using chemical analysis e.g. 1H NMR, 13C NMR and FT IR all data were in logic case. The copolymerization of Styrene with 10 and 25 mol% of DEAMVA has been implemented by free radical polymerization. The copolymers have been chemically and physically evaluated e.g. 1H NMR, FT IR, GPC, and DSC. Post polymerization modification of copolymer with 25 mol% (III b) was fabricated via the immobilization with Tryptophan, and has also been investigated by the same instrument used lately. Moreover, the responsive property of the posted polymer to pH has also been tested by UV-vis. Spectroscopy.
