Hydrogels Based on Rice Starch, Acrylic - and N, N'-Methylenbi Sacrylamide, Metacrylamides and Their Use in Agriculture

Abstract

Hydrogels containing soil and atmospheric moisture with hydrogel characteristics were synthesized by polymerizing polymers with acrylamide and methacrylamide, N,N-methylene-bis-acrylamide, and their physical and chemical properties were studied. The effects of temperature, the amount of oxidizing agent - N,N-methylene-bis-acrylamide in the reaction mixture, initiator concentration, and various solvents (water, ethyl alcohol, etc.) on the solubility of the obtained polymers in water were studied. The synthesized spatially structured polymers have been studied to form highly swelling hydrogels depending on the reaction conditions. Based on the samples obtained as a result of the research, the scientific basis for obtaining hydrogels that absorb moisture from the soil and atmosphere at a high level was developed. By modifying polymers with natural compounds, the possibility of obtaining hydrogels with a positive effect on the growth of cultivated plants in agriculture was investigated.
