Abstract
AbstractThe dielectric and physical‐mechanical properties of organophosphorus polyurethane ionomers based on the ethers and aminoethers of ortho‐phosphoric acid have been investigated. The influence of the content of ionogenic groups and polyphosphate structures on the dielectric properties of polyurethanes has been analyzed. It is shown that the values of dielectric permittivity and tangent of dielectric loss in a wide frequency range increase with the content of ionogenic groups in polyurethanes studied. In this case, the increase in conductivity is diffusive in nature and is due to the mobility of protons within the phosphate anion clusters. The compositions of samples with a combination of high dielectric properties and excellent physical‐mechanical and adhesion characteristics have been determined. These are samples in which polyphosphate structures are present in addition to phosphate anions.
