โœฆ Synopsis

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 differences in swelling behaviors of samples are discussed on the basis of their structural and physical differences.

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
