The study of polyacrylimide foams based on compositions of polyacrylamide hydrogels containing hollow corundum microspheres as fillers was carried out. The effect of fillers on the physical and mechanical properties and thermal stability of polyacrylimide foams has been studied. The structure and morphology of the obtained foam materials were studied by scanning electron microscopy, and the average cell size was established.

The influence of titanium dioxide filler on the physical, mechanical and dielectric properties of epoxy-novolac foams of the PEN-I brand has been studied. The dependences of the apparent density, thermomechanical characteristics, and water absorption of structural foams depending on the filler content are analyzed. It is established that by introducing dispersed additives, it is possible to regulate the dielectric constant within specified limits and with high accuracy.

The article presents the results of a systematic analysis of the electrical conductivity of nanocomposites based on high density polyethylene and carbon fillers such as carbon black and graphite. 13 nanoscale carbon fillers are used. The aim of the study was to select the most effective nanofillers from among the various types used. The efficiency of nanoparticles was evaluated not only by electrical conductivity data, but also by changes in the main physical and mechanical parameters. Such characteristics as electrical conductivity, breaking stress, elongation and melt fl ow index were studied. It is shown that the best nanofillers are Printex XE 2B carbon black and GS-2 graphite.

The possibility of using the conformational approach to describe the crystallization kinetics during melt-crystal phase transitions in an inhomogeneous temperature field and to determine the molar mass range corresponding to a change in the crystallization mechanism is shown using the example of PMS brand organosilicon liquids. It is established that the curve of dependence of the mean square of the dipole moment of a macromolecule on the average molar mass of an organosilicon polymer contains three sections, each of which has its own crystallization mechanism.

The results of investigation of dependence of physical and mechanical characteristics of disperse-filled polymer composite materials (DFPCM) based on EVA grade 11306-075 and rice straw powder with particle size of ~ 250 microns (RSP) on generalized parameters of their structure are presented. The calculation of the generalized parameters and the classification of DFPCM according to the type of structures were carried out.It has been shown that when filling EVA grade 11306–075 with RSP particles, depending on the type of structure, the tensile strength of DFPCM decreases by ~ 2 times (from 9.4 to 4.51 MPa), the tensile strain by more than ~ 10 times (from 275 up to 8%), and the value of the tensile modulus increases by ~ 18 times (from 42 to 750 MPa).To obtain DFPCM based on EVA filled with rice straw powder with optimal physical and mechanical properties, it is recommended to introduce RSP in the concentration range from 0.18 to 0.45 vol.p.
