A novel series of chitosan derivatives were synthesized via reaction of chitosan with carbonyl compounds and
grafted it’s by with different amine compounds substituted hydrogen. The produced polymers were characterized by different
analyses FTIR, 1HCNMR, XRD, DSC and TGA. Solubility in water as well as many solvent was investigated, antibacterial
activity of chitosan and its derivatives against two types of bacteria E. coli and S. aureus was also investigated. The results
showed that derivatives sort of have antibacterial activities against Esherichia coli (Gram negative) better than chitosan whilst
compound IX has better antibacterial against Staphylococcus aureus (Gram positive). SEM analysis showed that increase of
surface roughness with modification.
