POLYMER COMPOSITE MATERIALS: BASED ON POLYOLEFINS AND THEIR PROCESSING PRODUCTS, NATURAL MINERAL ROCKS AND WASTE, APPRETES (COATINGS)

The presented scientific research work deals with the production of polymer composite materials with complex operational properties based on polyolefins and their derivatives, local natural mineral rocks and their wastes, and dressings with various functionalities, and the study of a number of properties of the created materials. The influence of filler and sizing agent on a number of physical and mechanical properties of the resulting composites was studied. In order to improve the adhesion between the polymer matrix and the filler and obtain composites with higher physical and mechanical properties, a sizing agent is included in the system. A copolymer of maleic anhydride and vinyl acetate, which differs in functionality, was taken as a coupling agent. It has been established that the properties of the resulting polymer composites depend on various factors; this depends on the structure of the polymer matrix, the amount of filler and its dispersion properties, as well as the influence of the sizing agent on the interfacial layer. Depending on the properties of new generation composites created as a result of research, their areas of application are expanding.
