Prediction of physical aging in controlled-release coatings: the application of the relaxation coupling model to glassy cellulose acetate
The effect of physical aging on both the water transport properties and the mechanical properties of glassy cellulose acetate was investigated. Results indicate a reduction in the mechanical rate of relaxation as well as a reduction in the water permeability as the glass ages. A model which describe...
