Abstract
The phenolphthalein analog was introduced into the side chain of poly(4-hydroxystyrene) by a polymer reaction. The blended membrane which was made by means of poly{3-[3-(4-hydroxyphenyl)phthalidyl]-4-hydroxystyrene-co-4-hydroxystyrene} and cellulose acetate showed capability for the active and selective transport of alkali-metal ions at moderately low concentrations.
