INFLUENCE OF FILLER AND APPRETE ON THE PROPERTIES OF COMPOSITE BASED ON LOW DENSITY POLYETHYLENE AND MINERAL ROC “GIZIL ZOD”

The article produces a new generation of composites with different ratios of components based on lowdensity polyethylene (LDPE) and natural mineral from the village of Gızıl Zod in the Kelbajar region. The influence of the filler on the 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 heptene-1 with maleic anhydride was taken as a coupling agent (apprete). It has been established that the properties of the resulting polymer composites directly depend on various factors: the structure of the polymer matrix, the amount and dispersion properties of fillers, and the properties of the sizing agent formed and acting on the interfacial layer
