Abstract
The paper presents data on the preparation and study of hydrogels made of starch with citric acid as a cross-linking agent at concentrations from 1.2% to 19.8% (of starch mass) at different synthesis times. The hydrogels with hydromodule 1 : 10 and amount of citric acid 2.5% and 5% (of starch mass) under synthesis conditions of 5 hours have the highest water absorption capacity. Also the study of swelling kinetics, showed that the maximum water absorption capacity of hydrogel is reached during the first 4 h of being in water. The rheological properties were determined for the sample with the best water absorption index.
