In the chemical and petrochemical industry, the primary focus for workers in the upcoming years is to develop innovative and secure technologies and equipment that comply with stringent quality standards. This imperative encompasses the production of materials, devices, and other products that meet the highest global benchmarks in technical and economic aspects. Emphasizing the implementation of progressive technologies and advanced production methods is crucial for achieving substantial improvements in labor productivity across all sectors of the national economy, with special attention paid to the chemical industry. This paper work presents the results of a study on increasing the thermal stability of cellulose triacetate by introducing stabilizers into its composition. Regularities of plasticization of cellulose triacetate with low- and high-molecular compounds have been established. As a result, the deterioration of the physical and mechanical properties of polymer materials processed at high temperatures occurs due to thermo-oxidative degradation, which leads to changes in the composition of the main polymer chain and a decrease in molecular weight. The application of stabilizers is proposed to prevent this process at high temperatures. |
