磷腈聚合物是无机高分手中最有价值的一种,它是具有高弹性、热稳定性和耐燃性較好的合成材料。可惜的是磷氯鍵不太稳定,易起水解作用,因而限制了它的广泛应用。由于考虑到聚合物的氯原子可能被各种有机基团所取代,故可以通过聚合物的化学取代反应来改善其性能。我們除了用一般呲啶法和鈉醇法将聚氯化磷腈和正丁醇、丙烯醇等醇类化合物进行酯化外,还在Co~(60)Υ源和X射綫下进行輻照酯化。
Phosphazene polymer is one of the most valuable inorganic in the hand, it is a high flexibility, thermal stability and flame resistance of synthetic materials. Unfortunately, phosphorus-chlorine bond is not stable, easy to hydrolyze, thus limiting its wide range of applications. Due to the fact that the chlorine atoms of the polymer may be replaced by various kinds of organic groups, the performance of the polymer can be improved by a chemical substitution reaction of the polymer. In addition to the esterification of polychlorinated phosphazenes and alcohols such as n-butanol and allyl alcohol by the general pyridine method and the sodium alcohol method, we also conducted the esterification under the Co 60 Y source and the X-ray The
