Stabilizers of Some Polymer Materials Based on Sterically Hindered Phenols

Stabilizers of polymer materials are used to solve the problem of polymer degradation and durability. Over time, environmental elements such as heat, light, and atmospheric oxygen can destroy or damage the polymer material, and in this regard, polymer stabilizers play a protective role. Polymer stabilizers must be durable and withstand certain climatic conditions well throughout their service life. With the correct application of these stabilizers, the overall performance, durability, and safety are significantly improved, as the applied stabilizers guarantee the resilience and durability of the polymer material, preventing the deterioration of its physical and mechanical properties caused by external influences. In recent years, sterically hindered phenols and their functionally substituted derivatives, which can act as antioxidants, heat stabilizers, and other types of stabilizing compounds, have been increasingly used as such stabilizers. This paper analyzes the results of research in the field of developing new effective stabilizers for a number of polymer materials, such as polyvinyl chloride, polyethylene, and polypropylene. The main advantages and disadvantages of the described stabilizers are shown, and the results of the authors' own research in the field of obtaining new effective stabilizers are presented.
