Résumé
This study reports the preparation and characterizations of chitosan-azomethine derivatives containing oxazine ring as new crosslinked polymers. The novel chitosan derivatives have been prepared by functionalization with reactive benzoxazine precursors. Two types of aldehyde-terminated benzoxazine precursors have been synthesized using two different polyetheramines (Jeffamines), 4-hydroxybenzaldehyde, and paraformaldehyde. The benzoxazine precursors are covalently attached to chitosan via Schiff's base formation. Benzoxazine structure is confirmed by proton nuclear magnetic resonance spectroscopy (
