A hydrophilic/hydrophobic interpenetrating polymer network (IPN) of poly (vinyl alcohol) /polystyrene was prepared by conversion of the IPN of poly (vinyl acetate)/polystyrene. The hydrophilic/hydrophobic IPN was characterized by FT-IR and DSC, and the swelling ratios of the IPN in different solvents were measured.
