发明名称 RECOVERY OF POLYPHOSPHAZENE POLYACIDS OR ACID SALTS THEREOF
摘要 <p>A process for recovering a polyphosphazene polyacid or acid salt obtained by hydrolyzing a polyphosphazene having at least one ester moiety present in at least one substituent group. The polyphosphazene having at least one ester moiety present in at least one substituent group is hydrolyzed with a base in an organic solvent in the presence of water. The water is present in an amount effective to induce the agglomeration of particles of the synthesized polyphosphazene polyacid or acid salt, which enhances the separation of the polyphosphazene polyacid or acid salt from a polymer-free liquid organic phase. The polymer-free liquid organic phase then is separated from the polyphosphazene acid or acid salt, whereby the polyphosphazene acid or acid salt is recovered.</p>
