    摘要: Low or no chlorine content poly(aryloxyphosphazene) copolymers useful for fireproof foams are surprisingly produced in a one step process without use of excess phenoxide reactant over a shorter than conventional time period by (a) adding linear (NPCl 2 ) n to a mixture of phenoxides comprising alkali or alkaline earth metal phenoxide, alkylphenoxide and allylphenoxide in quantities such that the total of the phenoxides is the equivalent of the total chlorine atoms in the (NPCl 2 ) n and allylphenoxide is present in an amount equivalent to from about 2% to about 10% of the chlorine atoms in the (NPCl 2 ) n ; and (b) reacting the admixture formed in step (a) at a temperature ranging from about 280°F. to about 320°F. for a time period ranging from about 7 hours to about 10 hours.
