A process for producing an aryloxy-substituted phosphazene derivative represented by the formula (N.dbd.P).sub.n (OAr).sub.l Cl.sub.m-l R.sup.1.sub.p (III) which comprises reacting a chlorophosphazene derivative represented by the general formula (N.dbd.P).sub.n Cl.sub.m R.sup.1.sub.p (I) with, a hydroxy aryl compound represented by the general formula HOAr (II) where R.sup.1 represents hydroxy group, NH.sub.2 group, --OR.sup.4 group, --SR.sup.4 group or ##STR1## group, where R.sup.4, R.sup.5 and R.sup.6 represent independently an alkyl group, an alkenyl group, alkynyl group or an aryl group or one of R.sup.5 or R.sup.6 may be hydrogen or R.sup.5 and R.sup.6 may form, together with a nitrogen atom bonded thereto, a saturated or an unsaturated heterocyclic ring, n is an integer of 3 to 20, m is an integer of 1 to 2n, p is 2n-m, Ar represents substituted or unsubstituted phenyl, substituted or unsubstituted naphthyl, or substituted or unsubstituted N-maleimidophenyl, l is an integer of 1 to m, wherein the reaction is carried out under the presence of an acid acceptor and a pyridine derivative represented by the formula ##STR2## where Q.sup.1 and Q.sup.2 represent identical or different lower alkyl groups or constitute together with a nitrogen atom bonded thereto, a pyrrolidine ring, piperidine ring or morpholine ring.
A process for obtaining a substituted phosphazene, comprising
The process of claim 1, wherein the Ar group of the compound of formula (II) is ##STR39## wherein R.sup.2, q, and r are as described in claim 35;
The process of claim 1, wherein the Ar group of the compound of formula (II) is ##STR41## wherein R.sup.3 and s are as described in claim 35 and the acid acceptor is at least one selected from the group consisting of strong inorganic bases,
