Poly(anilino sulphamicphosphazenes) such as [NP(HNC6H5)2−x(HNC6H4SO3H)x]n for polymer (I) x=0.3 and for polymer (II) x=0.8 were prepared by the reaction of poly(anilinophosphazene) [NP(HNC6H5)2]n and sulphonic chloride HSO3Cl in tetrachloroethane solvent several timeS. Also, H protons in the polymer (I) and (II) were prepared from lithum hydroxide in aqueous solution. It was found, by chemical analysis, that the product prepared with (I) and (II) had compositions such as [NP(HNC6H5)1.7 (HNC6H4SO3H)0.1(HNC6H4SO3Li)0.2]n(III) and [NP(HNC6H5)1.2(HN-C6H4SO3Li)0.8]n(IV). Also, the resistivity of products (III) and (IV) were determined and found to be 3.3×107 and 1.5×107 Ωcm−1, respectively.
