filling

The properties of blends filled with polymers of a different structure and low molecular weight additives were analyzed. Additives selection is grounded. It was established that three-component polymer blends have a sufficient fluidity value, which ensures the ability of obtained materials to be processed. The influence of the composition and nature of the components on the physical and mechanical properties of obtained compositions was studied.

The paper suggests the solution to the urgent problem of increasing the level of environmental safety of industrial wastewater treatment from heavy metal using natural and modified bentonite.The use of spent bentonite in the processes of filling polymers is investigated. The aim of the research was to study the influence of fillers on the crosslinking course and functional properties of vulcanized elastomeric mixtures. Test research compositions included chloroprene rubber and chlorosulfonated polyethylene. Nanofillers were used as a strengthening substance.

The effect of filling on water uptake has been studied for coatings based on aqueous dispersion Acronal-290D and pigment part consisting of titanium dioxide and calcium carbonate. It was found that an increase in the pigment volume concentration is accompanied by an increase in the rate of water absorption, but the maximum value of water uptake is characterized by a minimum near the critical pigment volume concentration.

The influence of dispersed surface modified titanium oxide (IV) on the conditions of confirmation of unsaturated polyester resins and properties of composites was ascertained. The regimes of confirmation of polyester resins and detected activation role of filler for forming the composites with improved operational characteristics were determined.  Встановлено вплив дисперсного поверхнево модифікованого оксиду титану (IV) на умови тверднення ненасичених поліестерних смол та властивості композитів.
