Poly(vinyloxyacetic acid) and its metal salts show polyelectrolyte behaviour in water. The order of counterion binding to this polymer is K + > Na + > Li + > Ca 2+. The glass transition temperature (Tg) of poly (vinyloxyacetic acid ) with low ionic content and that of its metal salts are the same as that of poly (vinyl alcohol) whereas poly(vinyloxyacetic acid) with high ionic content shows an increased Tg.
