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

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
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 effect of physical aging on the gas permeability, fractional free volume (FFV), and positron annihilation lifetime spectroscopy (PALS) parameters of dense, isotropic poly(1-trimethylsilyl-1-propyne) (PTMSP) films synthesized with TaCl 5 and NbCl 5 was characterized. As-cast films were soaked in
