ABSTRACT

Synthetic polymers play an important role in the agricultural use as structural materials for creating a favorable environment for plant growth. Over the last few years the science of synthetic polymers has received great interest as one of the most exciting areas of polymer chemistry for the production of improved materials. The creation of multifunctional materials with prognosticates properties is important.
The main objective of the research was to develop methods for the preparation of transparent hydrogels filled with protein hydrolysate "Biostim" the use of such composite materials as stimulation of plant growth.
During of the works, samples were obtained with different concentrations of filler "Biostim" (0.5, 1, 1.5, 2 and 5 wt. %) the method of free-radical polymerization.
Confirmation of the presence of protein bands of composite materials filled with "Biostim" was determined on the spectrometer TENSOR37. The sample with the maximum content (5 mass. %) increased the elongation at perforation to 900%, compared with the unfilled composite materials.
When studying the kinetic parameters of sorption of the sample with a 5% share of filler also reached the best sorption characteristics in distilled water to 700 g/g and saline - up to 60 g/g.
