“…In addition, such features as resistance to oil and gas, resistance to most acids and bases, and satisfactory physicomechanical and technological characteristics make them indispensable materials for the production of a broad assortment of extrusion and casting products, which are characterized by high operational characteristics. Introduction of fillers, plasticizers, and stabilizers; mixing with other polymers; and chemical crosslinking provide new opportunities for expansion of the fields of their practical application as structural materials with desired characteristics [1][2][3][4].…”

“…However, analysis of the literature devoted to processing of composite materials and nanocomposites shows the absence of detailed analytical studies. This can be explained by the fact that many specialized companies do not reveal technological features of processing of composites or know-how of their development because of intense competition [4][5][6].…”

The results of a study of the effect of injection molding on the physicomechanical and technological properties of nanocomposites based on low density polyethylene functionalized with maleic anhydride and talc dressed with gg-aminopropyltriethoxysilane are presented. As the object of study, nanocomposites with 5.0 and 30 wt % of dressed talc were used. Properties such as breaking stress, elongation at break, flexural strength, and volumetric shrinkage were investigated. It was found that the introduction of dressed talc in the composition of chemically modified low density polyethylene contributed to some increase in the breaking stress and the flexural modulus of the nanocomposite. Experimental studies were carried out in a wide range of temperatures of the material cylinder and casting pressure. It was found that relatively high physical and mechanical properties were achieved in samples obtained at higher temperatures in the zones of the material cylinder. The casting pressure ranged from 50 to 150 MPa. It was found that relatively high physicomechanical and technological properties for nanocomposites with 5.0 and 30 wt % talc content were achieved at a temperature of the material cylinder in the zones of 110-130-160-180°C and a casting pressure of 150 MPa. A significant reduction in volumetric shrinkage is achieved in samples with 30 wt % talc content. The influence of mold temperature and holding time under pressure on the change in the properties of nanocomposites is considered. It is shown that the optimal mode in the cooling mold for samples with 5.0 wt % talc content is 50°C and the exposure time under pressure of 20 s, and for a nanocomposite with 30 wt % talc content, 50°C and holding time 10 s. The influence of the location of the gate device relative to the surface of the sample on the change in the properties of composite materials is studied. The scientific substantiation of the discovered patterns in changing the properties of nanocomposites is given.

“…As a rule, the demand includes high strength, heat resistance, impact resistance capability, wear resistance, fire resistance, etc. [1][2][3]. For a long time, many scientists tried to solve this problem directly in the process of industrial synthesis of homo-and copolymers, by loading various modifiers, fillers, and compiling a mixture of bipolar polymers [4,5].…”

A principled technological scheme for fine-dispersed aluminosilicate dressing process with various types of organosilicon compounds, as well as technological characteristics of dressing and obtaining of modified aluminosilicates are shown. Kaolin, talc, quartz, clinoptilolite, montmorillonite, vesuvian, bentonite were used as aluminosilicates. Research into physicomechanical properties of polymer composites revealed that the loading of unmodified kaolin into low density polyethylene leads to a decrease in the elongation and ultimate tensile stress with a maximum at 10% wt. filler content. However, the loading of 10% wt. of the dressed kaolin is accompanied by a noticeable improvement in the ultimate tensile stress, flexural strength of the composite in terms of elongation maintenance at a relatively high level. For a comparative properties' evaluation it showed the possibility of producing in principle dressed aluminosilicates with a wide range of organosilicon compounds. It went to show that out of 13 names of organosilicon compounds, chlorine-containing dressing sizes have a slight effect of enhancing the strength of composite materials.

“…В полимерной промышленности, в частности в области промышленного синтеза и переработки, все большее внимание ученых и специалистов стало уделяться формированию в мире новой технико-экономической политики. Вызвано это тем, что развитие современной промышленностиавтомобильной, авиационной, судостроительной, космической, военной, машиностроительной, электронной и т.д., выдвигает необходимость разработки инновационных полимерных композиционных материалов, удовлетворяющих различным уровням эксплуатационных требований [1][2][3][4]. Принимая во внимание многотоннажность производства термопластичных полиолефинов, основное внимание концентрируется на модификации их структуры и свойств.…”
