Bola študovaná príprava planárnych filmov karboxymethylcelulózy o rozdielnej molekulovej hmotnosti a rovnakom stupni substitúcie na produktech priemyselnej výroby firmy Herkules Inc. Filmy boli pripravované odlievaním z vodných roztokov na Petriho miskách a po dokonalej dehydratácii boli podrobené štúdiu kinetiky tvorby povrchovej napučanej vrstvičky v procese inkorporácie kvapalnej vody mikrointerferometrickou metodou. Z teplotných závislostí hrúbky povrchovej napučanej vrstvičky, difúzního koeficientu H2O a empirického člena RA,s v rovnici Uebberreitera a Asmussena boli pomocou vzťahu zavedeného Lapčíkom a Valkom vypočítané hodnoty vnútorných tlakov v sústavách obsahujúcich približne 50 % jednotlivých zložiek. |

There was studied: a preparation of planar film of carboxymethylcellulose with different molecular weight substitution. The study of the same degrees of substitution. The study of samples where of industrial origin – a specific product Hercules Inc. The films were prepared by method of plaster- casting from diluted solutions on Petri dishes at laboratory temperature. By this way prepared samples where subjected to swelling in liquid water at temperature range from twenty to thirty degrees centigrade. There were determinate of swelling parameters: integral mean diffusion coefficient of water in a carboxymethylcellulose, activated enthalpy of diffusion connecting swelling, activated enthalpy of swelling and expansion work of polymer under an action work of internal pressure. The value of the last one was determinate from the equation introduced by Lapčík, Valko earlier. |
