The reaction between poly (dichlorophosphazene), (NPCl2)n, and phenyllithium has been studied with changes in temperature, reaction time, media, and mole ratio of reactants and in the presence of chelate complexes. The results showed that the chlorine substitution reaction is a slow process, while chain cleavage is much faster and dominates the overall reaction pattern. The nucleophilic replacement of halogen atoms yields high polymers of formula NnPnClxPhy that contain up to 10% phenyl-substituent groups. The remaining chlorine atoms can be replaced by treatment with sodium trifluoroethoxide or n-butylamine. The properties and molecular structure of the products are discussed.
