一种新的聚磷腈反应中间体的制备及含C60基团聚磷腈的合成

聚磷腈的主链是由氮和磷原子以单、双键交替构成的聚合物, 每一个磷原子上连有两个侧基. 由于其具有多样化的独特性能, 如耐水、耐溶剂、耐油和良好的光、热稳定性、抗氧化性、生物相容性、耐辐射、耐低温、可生物降解、不燃烧和阻燃等性能而引起了人们的极大兴趣. 近来, 关于聚磷腈功能材料的研究相当活跃, 涉及阻燃材料、特种橡胶材料、生物医用材料、液晶以及光电功能材料等多个方面[1～4].

Syntheses of a Novel Intermediate Polyphosphazene and C60-contained Polyphosphazenes

In this paper, a novel synthetic strategy was developed to prepare functional polyphosphazenes. This strategy was successfully applied to synthesize the first C 60-contained polyphosphazenes. Thus, polyphosphazene that contains azido groups as the side groups was obtained by a direct reaction. And then the azido groups reacted with C 60 moieties to yield the C 60-contained polyphosphazenes. The polymers were well characterized and exhibit an excellent solubility in common organic solvents.
