SAFETY OF USING ISOPHTHALIC ACID AS A COMPONENT OF POLYMER MATERIALS

The widespread use of polymeric materials in various industries and fields of activity is explained by the thermal stability of polymers, their high strength characteristics, and the durability and reliability of synthetic materials. The introduction of additives can change the physical-mechanical, thermophysical, optical, electrical, frictional and other performance characteristics of the original (base) polymer. The purpose of the article is to investigate the safety of using isophthalic acid filler in a polymer composition. Methodology. Application of theoretical research methods, regulatory documents. Results. The spheres of polymeric materials application are considered. Ways of creating polymers with specified properties by introducing fillers into their composition, which change not only the operational characteristics, but also the physical and chemical characteristics of the original polymer are investigated. In view of the identification for danger of using isophthalic acid as a filler for phenylone, its physicochemical composition, stability, reactivity, toxicity, and environmental impact are studied. The measures and means of ensuring fire and explosion safety, means of controlling hazardous exposure, precautionary measures for personnel and personal protective equipment when working with isophthalic acid are considered. As a result of the research, it is possible to obtain an optimal polymer composition with improved plastic characteristics and safe properties. Scientific novelty. The possibility of obtaining an optimal polymer composition is shown: with improved plastic characteristics due to the addition of the biodegradable isophthalic acid filler fenilon to the polymer material; safe properties for humans and the environment, namely the absence of toxic substances release under the influence of heat, light and other external actions. Practical value. The resulting polycomposite material with updated plastic characteristics and safety properties can be used for further processing of secondary polymer raw materials.
