Název v původním jazyce
Kinetics of Dissolution of Na+[Carboxymethylcellulose] and Oxycellulose Mixture
Popis výsledku v původním jazyce
There was studied the kinetics of dissolution of solid films of NaCMC and OC prepared from their mixtures in water by fast plaster casting method on Petri dishes. The dependences of the kinetics parameters of the process (tQ, uOC, deltaH does not equal i,j, RAdelta,i) on the given polymer compositions were determined. It has been found, that internal pressure in the solid swollen layer decreased with increasing content of OC in the mixture as well as the activation enthalpy of diffusion connected with swelling deltaH does not equal D,s.
