Abstract
Polymers of intrinsic microporosity (PIMs) possess rigid and highly non-linear molecular structures. The contortion site of PIM-1 is provided by the monomer 5,5 ,6,6 -tetrahydroxy-3,3,3 ,3 -tetramethyl-1,1 -spirobisindane (TTSBI). The paper described the effect of synthetic conditions including catalyst and reaction time on the yield and purity of TTSBI. Then, PIM-1 was synthesized by TTSBI and 2,3,5,6-tetrafluorophthalonitrile in DMF at 60oC for 96h. The chemical structure of TTSBI and PIM-1 was characterized by 1H NMR and FT-IR. The gas separation properties of PIM-1 treated in different conditions were obtained. The optimized synthetic condition of TTSBI was that hydrochloric acid was chosen as catalyst to react for five hours at 105oC. PIM-1 had good solubility in chloroform. The PIM-1 membranes had good gas permeability coefficients for O2, N2, H2, CH4 and CO2. PIM-1 membrane treated by methanol solvent soaked or redissolved in chloroform showed outstanding gas permeability coefficient and a moderate selectivity.
