Research results of the modification mechanism of the Armenian minerals with fluorocontained olygomers are given. It is shown that, when treating of mineral fillers with fluoroalcon, a modified product is formed saving the structure of fillers with developed layers of fluoroalcon in which chlorine atoms are located on its periphery. It was established that the developed composites based on heterochained polymers and modified fillers are characterised by higher wear resistance, low friction coefficient, and improved strength properties.
