RECYCLING, MODIFICATION AND DEVELOPMENT OF NEW COMPOSITE MATERIALS BASED ON POLYMER WASTE

The review article considers the current problem of environmental pollution with polymer waste. To solve one of the highest priority tasks, their recycling is considered, which is advisable from an economic, practical and scientific point of view. An assessment of the resources of secondary polymeric raw materials was made. The main ways of utilization of polymeric waste are given. The features of polymer waste recycling methods are determined. The issues of modification of polymer wastes are considered and the main methods of compatibilization of polymer mixtures are shown. Particular attention is paid to the methods and mechanisms of compatibilization of polymer composites based on recycled thermoplastics and crumb rubber from waste tires as a means of obtaining new composite polymer materials with valuable performance properties. The dependence of the properties of polymer composites on the filler concentration, particle size and shape, surface treatment methods, type and content, modifying additives and compatibilizers is shown. The creation of polymer composites based on secondary polymers and fillers of various nature contributes to the solution of social and economic problems of polymer waste.
