Prediction of Physical Aging in Controlled-Release Coatings: The Application of the Relaxation Coupling Model to Glassy Cellulose Acetate
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1991-06)
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 ...
The Effect of Physical Aging on the Dissolution Rate of Anionic Polyelectrolytes
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1990-06)
The effect of physical aging on the dissolution and mechanical properties of hydroxypropyl methyl-cellulose phthalate (HPMCP) was investigated. Dissolution rate measurements were performed on films which, initially above ...
