The novel crosslinked chitosan derivative (CMCSCL) has been synthesized via carboxymethyl chitosan with pentaerythritol tris[3‐(1‐aziridinyl)propionate] (PEN) as crosslinking reagent. Its structure has been proved by Fourier transform infrared spectroscopy, X‐ray diffraction, differential scanning calorimetry, thermogravimetric analysis and atomic force micrograph. The mechanical properties and water uptake of CMCSCL films have been measured. The results show that CMCSCL film with 4% PEN crosslinker has a high tensile strength (TS) 17.1 MPa, 13.1% elongation at break, and 99% water uptake. The film with 6% PEN has a TS 15.2 MPa, 10.2% elongation at break, and 111% water uptake. The dosage of the crosslinking agent is the principal factor affecting the mechanical properties and water uptake of these films. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
