Description

Hydrogels, which have high modulus even with relatively high water content, were prepared by dissolving poly(vinyl alcohol) (PVA) with poly(styrene sulfonic acid) sodium salt (NaPSS) in an autoclave at elevated temperature and pressure, then dehydrating and swelling in water. The high modulus was mainly due to crosslinked structures formed by interpolymer complex not made of PVA crystallites. The contraction of blend gels, which are drawn and dried in the drawn state, is caused by contraction of oriented amorphous chains with absorption of water. The oriented amorphous chains are mainly fixed by the crosslink formed by the interpolymer complex not the PVA crystallites.
