title: Gelation of polyacrylic acid aqueous solutions and the measurement of viscosity.
abstract: A simple method is described for following changes in viscosity of concentrated aqueous solutions of polycarboxylic acids used in certain dental cements. The difference in behavior over several months between solutions of polyacrylic acid and related polyelectrolytes is discussed.
