Thermoplastic Polycomplexes of Metal Phosphate and Primary Amines

The reactions of oligomeric aluminoborophosphates with hexamethylenediamine and pentylamine are studied, as are the properties of the obtained products which are polycomplexes with the participation of hydrogen bonds, which is confirmed by the results of quantum chemical calculations. The changes in the relaxation properties of the polycomplexes are determined by the softening and flow temperatures measured by thermomechanical analysis. It is shown that the modification of polyphosphates by primary amines under mild conditions leads to an increase in the water resistance of the obtained polycomplexes.
