| Popis: | The compositions of alumoboro- and alumochromophosphate with a tetratomic alcohol, pentaerythritol, which is the component forming hydrogen and chemical bonds with the phosphate groups, are considered. The extremum dependence of the softening point on the concentration of pentaerythritol accompanied by a symbatic change in the moisture resistance is found. The heat and thermal resistance, oxygen index of the cured compositions, and bending strength of the composites reinforced by a basalt fabric are measured. The energy of the intermolecular bonds of the monomeric phosphate units with pentaerythritol is calculated, and computer modeling of the conformation of the complexes is performed. The higher chemical activity of alumochromophosphate in comparison with alumoborophosphate is determined. |
