Halogenated hydroxy-aryloxy phosphazenes and epoxy oligomers based on them

By partial substitution of the chlorine atoms in hexachlorocyclotriphosphazene for halophenols and subsequent reaction of the resulting halogenated phenoxy phosphazene and 2,2-di(4-hydroxyphenyl)propane monophenolate hydtoxy-aryloxy phosphazenes were synthesized with a molecular weight of 1100-1400 g mol-1. Epoxide oligomers (epoxy number of 6-8%), which are cured with the formation of non-combustible compositions [PV-0 class of resistance to combustion according to State Standard (GOST 28157-89)], were obtained by reaction of these compounds with epichlorohydrin. Introduction of 5-50 wt% halogenated epoxyphophazene oligomers in industrial resin ED-20 can significantly improve the fl ame resistance of compositions based on these compounds.

Phosphazenes on diatomaceous earths in water adsorption

Hexachlorocyclotriphosphazene (T) and poly-bis-(trifluoroethoxy) phosphazene (A) deposited separately on wide-pore kieselguhr supports result in composite adsorbents of an increased adsorption capacity for water vapour per unit surface area. Deposition alters the adsorption behaviour of T and A themselves due to high dispersion and conformation changes of polymer chains within the pores in comparison with the initial solid state.
