Vijayalakshmi, SP and Madras, Giridhar (2006) Effect of pH, Concentration and Solvents on the Ultrasonic Degradation of Poly(vinyl Alcohol). In: Journal of Applied Polymer Science, 100 (6). pp. 4888-4892.
The ultrasonic degradation of poly(vinyl alcohol) was investigated at different pHs of solvent, in different water/solvent binary mixtures and at different polymer concentrations. Samples were analyzed by gel permeation chromatography. The degradation rate coefficients were determined by applying a continuous distribution model. Higher degradation rate was obtained at extremes of pH, in better solvents and at lower polymer concentration. The results obtained have been explained and discussed.
