Cardo聚芳醚酮共聚物的气体透过行为

作者用溶液缩聚方法合成了一系列含Ｃａｒｄｏ侧基的聚芳醚酮（ＰＥＫ—Ｃ）共聚物，研究了氢气、氮气和氧气的透过速率随共聚组成的变化规律，研究结果表明，此系列共聚物的气体透过速率随共聚组成呈Ｓ形关系变化，并且与共聚物的自由体积参数之间有较好的线性相关性

STUDY ON GAS PERMEABILITY BEHAVIOR FOR CARDO POLYARYLETHERKETONE COPOLYMERS

series of random PEK with cardo group copolymers were synthesized by reaction of mixture of phenolphthalein(PPH) and 3,3' -bis(4-hydroxyphenyl) -isobenzopyrrolidone(HPP) with equivalent molar bis(4-nitrophenyl) ketone(DNBP).The permeabilities of these copolymers to hydrogen, nitrogen and oxygen were observed to vary with HPP molar content in S-form different from other random copolymer systems reported previously. This peculiar phenomenon was explained according to polymer free volume, chain flexibility and strong intermolecular hydrogen-bond interaction.
