INTRODUCTIONThe important environmental issues that are extensively discussed at the present day include the salvation of nature from debris, the direction of development of the industry of biodegradable polymeric materials, and the rates of annual output [1-4].It is known that most of the plastics used in the global production are based on products of processing of hydrocarbon-containing raw materials (propylene, ethylene, and other organic compounds). However, the further focusing on these technologies is attributed to the rise in prices for hydrocarbon-containing raw materials and negative impacts on the environment. In addition, the amount of plastic waste also increases; the waste disposal requires studies on the development of technologies for the production of stable biodegradable plastics for various purposes. This direction is consistent with the modern concept of improvement and development of the production of useful goods from waste. These raw materials include biological waste; prior to use, it must be processed and modified by physicochemical methods [5].The previous studies were primarily focused on the design of polymeric materials that are resistant to environmental factors. At present, there is a new approach to the development of polymeric materials; it is based on maintaining their performance characteristics only in the period of their use. Despite all the difficulties faced by scientists, this direction of polymer materials science is part of their research interests, as evidenced by recent publications [6].Modern biopolymers can be produced from both renewable natural resources and conventional raw materials, i.e., petrochemicals [7]. At present, films based on natural biodegradable polymers, such as cellulose, chitosan, gelatin, polypeptides, casein, and soybean, are commonly used in the food industry [8-11]. Of particular interest is starch because it is the cheapest raw material and the main sources of its industrial production are potatoes, wheat, corn, rice, maize, and some other plants [12-14].Russian scientists have developed approaches to the preparation of biodegradable polymers based on enzymatic hydrolysate of keratin waste [15].A research trend of high priority is the development of new approaches to the production of biodegradable polymers exhibiting a high rate of biodegradation, enhanced performance characteristics, and a low cost.The aim of this study is to analyze the structural and mechanical properties and micromorphological features of polymer films based on hydrocolloids of vegetable origin that are used for the production of biodegradable polymers.
