[P1.038] Experimental data at 35°C and modelling; Sorption and diffusion of gases and vapors in poly (exo,endo-,4-bis(trimethylsilyl)tricyclononene)

The products of the addition type polymerization of the derivatives of norbornene represent a group of polymers of high permeability and high free volume. These polymers show solubility-controlled permeation, in which the influence of diffusivity is minor as compared to that of solubility. In this work, the sorption of methane, nitrogen, carbon dioxide, alkane and alkene vapors in poly(exo,endo-3,4-bis(trimethylsilyl)tricyclononene) has been studied at 35.0 ºC with the differential pressure decay technique up to the absolute pressure of ca. 10 atm
