Study of the effect of intumescent complex compounds on the basis of aminoderivatives of 2,4,8,10-tetraoxа-3,9-diphosphaspiro[5,5] undecane on the flame retardant properties and water resistance of the ethylene vinyl acetate copolymer in the flame retardant polymer compositions. The structure of intumescent compounds has been confirmed by the methods of elemental analysis and IR spectroscopy, the flame retardant properties of the intumescent systems have been investigated using the method of thermogravimetric analysis. Methods of synthesis of intumescent compounds based on 2,4,8,10-tetraoxа-3,9-diphosphaspiro[5,5]undecane and urea, melamine, dicyandiamidе and mixtures there of have been developed. The synthesized compounds have been shown to enhance the flame retardant properties of the ethylene vinyl acetate copolymer, exhibit an intumescent effect and participate in the construction of a char thermal insulation layer. It has been shown that the water resistance of fire retardant systems with the participation of intumescent complex compounds is much higher than the systems of ammonium polyphosphate / melamine / pentaerythritol composition. The expansion coefficient of intumescent systems containing of intumescent compounds to decrease by 10 - 20% after hydrothermal effects, while, as the expansion coefficient of the traditional intumescent system  in the same conditions is reduced by 40%. According to the results of accelerated hydrothermal tests, the stability of polymeric intumescent coatings with the participation of intumescent complex compounds to the action of moisture under conditions of temperature difference was determined. The obtained results indicate the prospect of using the investigated intumescent compounds for the creation of new technologies of intumescent coatings for wood with a long operation life.
