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

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 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

Cross-linkable poly[1-(trimethylsilyl)-1-propyne] (PTMSP) films were cast from toluene solutions containing PTMSP and either 4,4 -diazidobenzophenone or 4,4 -(hexafluoroisopropylidene)diphenyl azide. The composite films were clear and homogeneous and were cross-linked by UV irradiation at room tempe
