The solubility, diffusivity, and permeability of ethylbenzene in poly(1trimethylsilyl-1-propyne) (PTMSP) at 35, 45 and 55 ยฐC were determined using kinetic gravimetric sorption and pure gas permeation methods. Ethylbenzene solubility in PTMSP was well described by the generalized dual-mode model with

The bonded constants in the DREIDING force field have been parameterized for poly[1-(trimethylsilyl)-1-propyne] (PTMSP) from AM1 calculations of the dimer. The resultant force field has been validated through the simulation of amorphous cell density and x-ray data (d-spacing) and used to obtain diff
The diffusion coefficient of ethanol and of n-pentane in PTMSP, at 27ะC, was measured as a function of concentration up to a penetrant content of about 12% by weight, for polymer samples obtained through different processes; differential sorptions and desorptions with vapor phases were considered. I
Pure gas solubility and permeability of H 2 , O 2 , N 2 , CO 2 , CH 4 , C 2 H 6 , C 3 H 8 , CF 4 , C 2 F 6 , and C 3 F 8 in poly(1-trimethylsilyl-1-propyne) (PTMSP) were determined as a function of pressure at 35ยฐC. Permeability coefficients of the perfluorinated penetrants are approximately an orde
