The solubility, diffusivity, and permeability of ethylbenzene in poly(1trimethylsilyl-1-propyne) (PTMSP) at 35, 45 and 55 Β°C 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 gas permeation properties of poly(1-trimethylsilyl-1-propyne) (PTMSP), poly(1-phenyl-1-propyne) (PPP), and blends of PTMSP and PPP have been determined with hydrocarbon/ hydrogen mixtures, For a glassy polymer, PTMSP has unusual gas permeation properties which result from its very high free volu
The poly(1-trimethylsilyl-1-propyne) (PMSP) has the potential to be an important membrane gas separation material due to the fact that it has the highest gas permeability of all polymeric membranes. One problem with PMSP is a decrease in the gas permeability with age. In order to understand the agin
Poly(1-trimethylsilyl-1-propyne) (PTMSP), a high free-volume glassy disubstituted polyacetylene, has the highest gas permeabilities of all known polymers. The high gas permeabilities in PTMSP result from its very high excess free volume and connectivity of free volume elements. Permeability coeffici
