Crystallization of poly(vinyl alcohol) during solvent removal: Infrared characterization and mathematical modeling
Wong, Sim-Siong; Altınkaya, Sacide; Mallapragada, Surya K. (Wiley, 2007-04)Crystallization of semicrystalline polymer films during drying has a significant effect on the rate of solvent removal. Understanding and controlling the crystallization kinetics is important in controlling residual solvent ... -
Drying of semicrystalline polymers: Mathematical modeling and experimental characterization of poly(vinyl alcohol) films
Wong, Sim-Siong; Altınkaya, Sacide; Mallapragada, Surya K. (Elsevier, 2004-07)A mathematical model was developed to predict the drying mechanism of semicrystalline polymers involving multiple solvents. Since drying of semicrystalline polymers can be accompanied by changes in polymer degree of ... -
Multi-Zone drying schemes for lowering the residual solvent content during multi-component drying of semicrystalline polymers
Wong, Sim-Siong; Altınkaya, Sacide; Mallapragada, Surya K. (Taylor & Francis, 2007-06)The development of a glassy skin in multicomponent semicrystalline polymer systems limits the diffusion of solvents out of the system and increases residual solvent levels. Based on the results of a mathematical model that ... -
Understanding the effect of skin formation on the removal of solvents from semicrystalline polymers
Wong, Sim-Siong; Alsoy Altınkaya, Sacide; Mallapragada, Surya K. (Wiley, 2005-11)The effect of glassy skin formation on the drying of semicrystalline polymers was investigated with a comprehensive mathematical model developed for multicomponent systems. Polymers with high glass-transition temperatures ...
