CHEMISTRY AND CHEMICAL ENGINEERING
The purpose of this study is the synthesis and study of modified sulfur concrete for use in industrial construction. To achieve this goal, sulfur concrete based on gossypol resin and pyrolysis distillate was modified and studied. The strength properties of sulfur-based concrete obtained from sulfur modified with gossypol resin and pyrolysis distillate were investigated. For the addition to sulfur concrete, industrial waste was used as a finely dispersed filler - fly ash from the Angren TPP and phosphogypsum generated at Ammophos-Maxam JSC. It was found that the best strength results correspond to sulfur-based concrete modified with gossypol resin using an …

CHEMISTRY AND CHEMICAL ENGINEERING
The results of a study present the effect of new modified ingredients on the complex of properties of composite elastomeric materials. Methods for modifying mineral fillers have developed. It found that the introduction of modified ingredients into the composition of elastomeric compositions enhances the interfacial interaction at the “rubber-filler” interface and the formation of additional bonds between rubber macromolecules and functional groups, resulting in an improvement in the complex of properties of the compositions. New accelerators, activators for vulcanization of rubbers and plasticizers with stabilizing properties have proposed, and their optimal contents in the composition have determined.
