Synthesize and properties of photosensitive organic solvent soluble acylated chitosan derivatives (2)

A chitosan derivative carrying the benzene group was synthesized by the acylation reaction in the mild conditions. The chemical structures and physical properties of the compounds were characterized in detail. The chitosan derivatives were amorphous comparing with chitosan. The photopolymerization capability of chitosan derivative was also carried out by real-time infrared (RTIR) spectra, and it also has the own ability to photopolymer without photoinitiator under UV irradiation. The derivative had good ultraviolet absorption at 280 nm and good solubility in organic solvents.
