Abstract: (2-Hydroxy-3-butoxy)propyl hydroxypropyl chitosan (2-H-3-B-P-HPCS) was synthesized to prepare 2-H-3-B-P-HPCS/polyethylene glycol (2-H-3-B-P-HPCS/PEG) interpenetrating polymer network(IPN) hydrogels. The factors that could influence swelling properties of 2-H-3-B-P-HPCS/PEG IPN hydrogels were studied, such as concentration of 2-H-3-B-P-HPCS, reaction temperature, amount of PEG and glutaral. The 2-H-3-B-P-HPCS/PEG IPN hydrogels were investigated by SEM and IR. Aciclovir as a model drug was used to study the release performance. The results show that 2-H-3-B-P-HPCS/PEG IPN hydrogels have good swelling property, pH sensibility and drug releasing ability and can be used for a new drug carrier.

Key words: (hydroxy-butoxy)propyl-hydroxypropyl chitosan, polyethylene glycol, hydrogel, drug release
