Abstract
An apparatus to monitor changes in shrinking gels is described. Gellan gels (1 or 2%) were immersed in acetone and their shrinkage was monitored for ∼1.5-2 h. Typical weight ratio versus time curves were plotted and linearized. The weight loss parameters k1 and k2 were determined and the rate of initial loss was calculated. Changes in mechanical (stress at failure) and optical (transmittance) properties were recorded with time and found to be correlated. Data on changes in the optical properties of shrinking gels sufficed to estimate changes in their strength.
