Abstract

In the interaction of high-molecular ammonium polyphosphate with polyethylene polyamine, thermoplastic polymers with Tg = 46.3–50.7°C, Tsoft= 43–92°C, Tflow= 85–152°C are obtained. Thermal, heat resistance, moisture resistance, and the degree of crystallinity depending on the concentration of polyethylene polyamine are measured. The bending strength of polymers and reinforced composites is measured. A chemical scheme for the formation of a polycomplex is proposed and its structure is considered.
