Abstract
The thermal effects of dissolution of dextran in water and mixing of water with dimethylacetamide are measured by calorimetry and the thermal effect of precipitation of dextran at 298 K is calculated. A thermochemical method of determining the structural changes that take place during dissolution and precipitation of the polymer is proposed.
