Abstract

It was found that T-2 fireproofing compound, a mixture of methylphosphonic acid diamide ammonium salt and ammonium chloride, added to PETP alters the direction of the chemical processes in the basic stage of thermal decomposition of the polymer and increases the oxidative stability of carbonized residues, which decreases the inflammability of PETP. The oxygen index of protected PETP is 27–29% with a 5–7% concentration of T-2 fireproofing compound.
