STUDY OF CHEMICAL TECHNOLOGY FOR THE PRODUCTION OF HIGH-SWELLING POLYMER HYDROGELS (HSPH)

Abstract

One of the ways of water management in agriculture is the use of highly swelling polymer hydrogels (HSPH). New hydrogels based on ech, ammonia and gipan were produced. An upward change in the amount of cross-linking agent in the gel, in our case from 0.1 to 9%, also affects the increase in cross-linking of the main chains of acrylic acid and, as a consequence, a decrease in sorption. Sorption is explained not only by gel-ion ion exchange, but also by complex formation between the polymer structure and the ions of these metals, or electrostatic interaction. During the study, it was found that the size of the polymer grain has a noticeable effect on the static exchange capacity. As the polymer grain decreases, the static capacity increases. The influence of factors (temperature, concentration, etc.) on the degree of swelling of hydrogel has been studied. As a result of systematic studies of the produced polymers, further directions for research of the developed complex structural polymers are shown. The proposed field of application: agriculture, metallurgical industry, medicine, cosmetology, household chemistry.
