chains, which in turn supported the presence of the junction zones
by the double helix formation in the hydrogel.
An aqueous solution of the xerogel, which was prepared by
dissolution in NaOH aq., followed by neutralization with acetic acid
to pH 5.5-6.5 (Fig. 4.6a), gradually turned into the hydrogel form
as shown in Fig. 4.6b. These cycles were able to be repeated up to
five times. When the standard iodine-iodide solution was added
to the neutralized solution immediately after it was prepared by
the same procedure as above and the resulting mixture was kept
standing, the re-hydrogelation did not take place (Fig. 4.6c). In this
