The interrelation of physico-mechanical and technological characteristics of newly created nanocomposites on the basis of polypropylene (PP)/polyamide (PA-6) mixture with PVP-modified montmorillonite has been investigated. The significant impact of modified polyamide on technological, physical and mechanical properties and heat resistance of polypropylene has been determined. It has been established that the melt flow index of the resulting composites increases by more than 2 times, compared with pure PP.

The paper determines the influence of polymer modifier (poly(vinyl chloride)) and finely dispersed inorganic filler on the elastic-deformation and thermophysical properties of polyester materials. The research discovers the change of deformation modulus, elasticity modulus, high elasticity modulus, surface hardness, Vicat softening point, and technological shrinkage of modified polyester composites filled with calcium carbonate and aluminum oxide

In our time, the use of bitumen modified with epoxy compounds is considered as an
effective means of improving the durability of road pavement. Given the rather long duration
of modification of road bitumen epoxy rapeseed oil (EPO), we studied the processes of
modifying bitumen using ultrasonic cavitation. For research, road bitumen modified with
rapeseed oil epoxy using cavitation and without it. Cavitation in the process of modification of
road bitumen was used to reduce the modification time.
