The swelling behavior of interpenetrating polymer networks (IPNs) composed of poly(viny1 alcohol) (PVA) and poly(acry1ic acid) (PAA) in water was studied. The PVA/ PAA IPN gels were prepared by four synthetic methods. The swelling behaviors of these IPNs made by different methods were compared. The

A series of poly(acry1ic acid) (PAA)-poly(viny1 alcohol) (PVA) semiinterpenetrating (SIPN) and interpenetrating (IPN) polymer network membranes were prepared by crosslinking PVA alone or by crosslinking both PVA and PAA. Glutaraldehyde and ethylene glycol were used as crosslinking agents for the PVA
## SYNOPSIS T h e swelling behavior of novel pH-and temperature-sensitive interpenetrating polymer networks (IPNs) composed of poly(viny1 alcohol) (PVA) and poly(acry1ic acid) (PAAc) in water was investigated. The PVA/PAAc IPN hydrogels were synthesized by UV irradiation, followed by a repetitive
The swelling behaviors of poly(vinyl alcohol) -poly(acrylic acid) (PVA-PAAc) interpenetrating networks (IPN) hydrogels in the presence of electrolytes were studied. The ionized carboxylic group within IPN hydrogels at pH 7 strongly interacted with electrolytes in the medium and caused anomalous swel
