酚酞型聚芳醚腈砜的合成与性能研究

Synthesis and properties of phenolphthalein type poly(arylene ether nitrile sulfone)s

以酚酞、２，６二卤苯甲腈、４，４’，二氯二苯砜和４，４’，二羟基二苯砜为主要原料进行共缩聚反应，合成了酚酞型聚芳醚腈砜（ＰＰ－ＰＥＮＳ）。采用红外光谱、热分析等方法对共聚物的结构、热氧稳定性和玻璃化转变温度进行了表征。

The phenolphthalein type poly(arylene ether nitrile sulfone)s (PP PENS)were synthesized by copolycondensation of phenolphthalein,2,6 dihalogenbenzonitrile,4,4' dichlordiphenylsulphone and 4,4' dihydroxydiphenylsulphone.The infrared spectra and thermal analysis were used to characterize the structure,thermo oxidative stability and glass transition temperature of the copolymers.The effects of phenolphthalein structural unit and cyano content on the properties of PP PENS were also discussed.
