Аннотация:
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. © Pleiades Publishing, Ltd., 2013.
