Novel hydrogels were prepared from carboxymethyl cellulose(CMC) sodium salt by crosslinking with
polyethylene glycoldiglycidyl ether(PEGDE).The detailed structures of the hydrogels were determined
via FTIR and solid-stat eNMR spectroscopic analyses.Increasing the feed ratio of PEGDE to CMC in the
reaction mixture led to anincrease in the crosslinking degree, which enhanced the physical strength
of the hydrogels.The hydrogels exhibited enzyme degradability,
