series of cardo polyaryletlierketones containing alkyl substituents of diffrent kind and number were synthesized by "one-step" solution polycondensation reaction of his (4-nitrophenyl) ketone(DNBP) with phenolphthalein, o-cresophthalein,2', 5', 2", 5"-tetramethylphenolphthalein and thymolphthalein. Their chemical structure and aggregation structure were confirmed by FT-IR, 1H-NMR, differential scanning calorimetry, WAXD and density. The experimental result showed that polymeric free volume and segment flexibility varied greatly with position,king and number of substituents.
