Abstract
The growing anthropogenic load on the lithosphere is currently characterized by the alienation of huge areas for solid domestic waste. One of the most common pollutants is traditional plastics with a degradation period of over 100 years. In connection with the increasing environmental requirements, polymer materials, along with a high set of technological and operational parameters, must be environmentally friendly and biodegradable. The development of polymer composite materials that undergo accelerated physicochemical and biological changes in the natural environment due to the introduction of biodegradable additives is one of the potential methods for processing synthetic materials and ensures the release of significant areas of fertile soils and lands from the steadily increasing amount of polymer waste. The use of adipic acid esters as PVC plasticizers contributes to the production of biodegradable composites. The article describes a method for obtaining new esters of adipic acid, presents the results of studying their properties for practical use in PVC composites, and assesses the economic efficiency of preventing damage to the environment when using them.

The following composition was prepared for testing: 100 parts by weight of PVC; The synthesis of unsymmetrical adipates of ethoxylated alcohols was carried out by 42 parts by weight of the plasticizer; 3 parts by weight of calcium stearate stabilizer
The conducted thermoanalytical studies have shown that the developed additives are characterized by high thermal stability, good manufacturability, and a significant decrease in the glass transition temperature of polyvinyl chloride
Summary
Environmental pollution as a result of human activities leads to a deterioration in the health indicators of the population. As the most popular and widespread, make a significant contribution to the deterioration of the ecological situation [5,6,7,8]. The disposal of polymer products after operation most often occurs at solid waste landfills or is spontaneous. Soil pollution leads to degradation of the soil cover, withdrawal of land from agricultural use, and significant financial costs for the implementation of measures for the remediation of contaminated land [9,10,11,12]. Soil contamination with waste polymer materials poses a significant danger due to the migration ability of some toxic additives [13,14]
