Shantarovich, Institute of Chemical Physics, Russia - shant@chph.ras.ru Polymers with intrinsic microporosity (PIMs) and PIM- polyimides form a new class of advanced materials for membrane gas separation. They are distinguished by several excellent properties: a good combination of permeability and permselectivity (the data points are above Robeson upper bounds for various gas pairs: O2/N2, CO2/CH4, CO2/N2), relatively high gas permeability (e.g. P(O2)=1600 Barrer), the largest reported gas and vapor solubility coefficients, large free volume, unusual possibility to control their transport parameters by film casting protocol, good film forming properties. In the presentation a survey of different transport and thermodynamic parameters in these polymers will be disclosed and discussed: relative contribution of solubility and diffusion coefficients to permeability, temperature dependence of the permeability coefficients, the effects of chloroform, methanol and water on the observed permeability, the results of the study of sorption thermodynamics in these polymers using the inverse gas chromatographic method, free volume study by means of positron annihilation lifetime spectroscopy.
Gas Separation II – 5 Tuesday July 15, 4:30 PM-5:00 PM, Kaua’i Addition-Type Polynorbornene with Si(CH3)3 Side Groups: Detailed Study of Gas Permeation and Thermodynamic Properties L. Starannikova, Institute of Petrochemical Synthesis, Russia - Luda@ips.ac.ru M. Pilipenko, Institute of Petrochemical Synthesis, Russia - Luda@ips.ac.ru N. Belov, Institute of Petrochemical Synthesis, Russia - belovna@gmail.ru Y. Yampolskii (Speaker), Institute of Petrochemical Synthesis, Russia - Yampol@ips.ac.ru M. Gringolts, Institute of Petrochemical Synthesis, Russia - gringol@ips.ac.ru E. Finkelshtein, Institute of Petrochemical Synthesis, Russia - fin@ips.ac.ru Polymerization of norbornene bearing Si(CH3)3 groups in the 5 position with the opening of double bonds results in creation of a novel high free volume, highly permeable polymer addition type poly(trimethylsilyl norbornene) (PTMSN). By accurate selection of the ratios catalyst/co-catalyst and monomer/catalyst the samples with increased molecular mass (about 400,000) and good film forming properties can be obtained. Transport parameters of PTMSN were measured using the gas chromatographic and mass spectrometric methods for different gases (H2, He, O2, N2, CO2, CH4, C2H6, C3H8, n-C4H10). Temperature dependence of the permeability coefficients (P) indicated that low activation energies of permeation (EP) and diffusion (ED) are characteristic for PTMSN. In some cases (CO2, C2H6) negative EP values were observed. Thermodynamics of vapor sorption in this polymer was studied using the inverse gas chromatography method. It was shown that PTMSN is characterized by very large solubility coefficients S similar to those of poly(trimethylsilyl propyne) (PTMSP). The comparison of the P, D, and S values of these highly permeable polymers showed that the greater permeability of PTMSP is determined by the larger D values. Application of different approaches for the determination of the size of microcavities in PTMSN indicated that this polymer is characterized by large size of microcavity (800- 1200 Angstroms 3 ). Possible applications of this novel polymer as a material for gas separation membranes will be considered.
