Abstract
A process for producing an aryloxy-substituted phosphazene derivative represented by the formula EQU (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 EQU (N.dbd.P).sub.n Cl.sub.m R.sup.1.sub.p (I) with, a hydroxy aryl compound represented by the general formula EQU HOAr (II) where PA1 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, PA1 n is an integer of 3 to 20, PA1 m is an integer of 1 to 2n, PA1 p is 2n-m, PA1 Ar represents substituted or unsubstituted phenyl, substituted or unsubstituted naphthyl, or substituted or unsubstituted N-maleimidophenyl, PA1 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.…
