摘要：
The graft copolymerization of the vinyl monomers onto chitosan was confirmed by FTIR and DMTA. The chitosan used was also characterized by DMTA, which allowed addressing some questions related to the typical thermal transitions of this biopolymer. The swelling capacity of the membranes was also determined. The chitosan-graft-AA-graft-HEMA with an equimolar ratio of HEMA and AA kept good swelling capacity without compromising its physical stability, which suggests it to be the best matrix for drug delivery systems.
