| Title of the article | Study of hydrostatic pressure on the structure and properties of epoxy rubber polymers with the “shape memory” effect |
| Abstract. | One of the problems in producing epoxy compositions, especially in the presence of high-viscosity modifiers, is the compatibility of the components. Increasing the level of compatibility ensures a positive change in both technological and operational characteristics of the compositions and the polymer. The purpose of the work is to study the effect of physical modification (high hydrostatic pressure) on high-viscosity epoxy rubber oligomer compositions to increase the level of their homogeneity and physical and mechanical characteristics of epoxy polymers. The objectives of the study are: to determine changes in the structural and strength parameters of epoxy polymers as a result of physical modification. It has been established that a change in hydrostatic pressure affects both the change in structure: molecular weight of interstitial fragments (Mc) and effective density of polymer network nodes (Vc), glass transition temperature (Tс), and strength indicators: tensile strength (?p), modulus of elasticity (E) and relative highly elastic deformation (?в.э.). The significance of the results obtained for the construction industry lies in expanding the possibilities of changing manufactured industrial modifiers for the production of various composite materials, for example, shape memory couplings for connecting pipelines, including those made of dissimilar materials. |
