ABSTRACT

The sources of scientific literature on the research have been investigated, various approaches to the processing and modification of polymers have been analyzed, and the main direction of the study has been identified. The changes in the properties of thin layers of industrially produced low-density polyethylene (LDPE) grades 10803-20 and 16603-01operating01 operating under different climatic conditions have been studied having, and it has been determined that changes with different intensities occur in the structure and in this connection in the physical and mechanical properties of LDPE that was in operation at different time intervals and in different climatic conditions of the Absheron Peninsula and the Aran region: melt flow index of polymer alloy, tensile strength at break, relative extension, and values of the indicator sreredeteriorate ing. sreredeteriorate. Inpolymerm,samplareasis formed 24,2 – 28,6% of the insoluble phase and as a result of oxidation up to  12,3 – 16,8�rbonyl, HDD,,ox,y,l and other functional groups.
