Abstract
The paper presents a comparative analysis of the properties of biodegradable and synthetic polymer materials. The purpose of the research was to determine the physical and mechanical characteristics of biodegradable and synthetic polymers: water absorption, puncture resistance, deformation strength and thermophysical characteristics of various biodegradable samples based on polylactides (PLA) and synthetic polymer samples (polypropylene and polyethylene) in order to consider the possibility of improving the strength properties of finished products. The paper also presents the results of a study on the water-absorbing ability of polymer materials of various nature. It describes the results of tests to establish temperature and time parameters of polylactide processing by the melt production method. The authors analyzed the data obtained by the DSC method to determine relaxation and phase transitions occurring in the polymer during thermolysis. In addition, the paper considers environmental aspects of the practical application of these polymer materials. During the experiment, the authors have studied the chemical properties of biodegradable materials based on polylactides (PLA) produced in China, carried out a comparative analysis of the physical and mechanical characteristics of the synthetic and biodegradable polymers under study. The authors have outlined main advantages and disadvantages of the polymer samples under study and made conclusions about the possibility and safety of using the presented materials in various sectors of the national economy. The experimental results have shown that synthetic polymer materials are superior to biodegradable ones in all basic values of physical and mechanical characteristics, but at the same time they are inferior in environmental friendliness of their use. It is noted that in order to improve the operational properties of finished products, in case of biodegradable polymers it is recommended to use strengthening and hydrophobic additives.
Keywords
