For the first time, the effect of asymmetry of the membrane transport was studied for organic solvents and solutes upon their nanofiltration through the plasma-modified membranes based on poly(1-trimethylsilyl-1-propyne) (PTMSP). Plasma treatment is

To improve organic solvent preferential permeation of poly[1-(trimethylsilyl)-1-propyne] (PTMSP) and to provide efficient separation of dilute 1-butanol/water mixtures, the membranes were modified by the addition of minor amounts of a soft elastomeri

For the first time, the utilization of negative retention in organic solvent nanofiltration (OSN) for solute fractionation was proposed and realized. Using membranes made of poly[1-(trimethylsilyl)-1-propyne] (PTMSP) and ethanol as a solvent, this pr

The extra high free volume glassy polymer poly[1-(trimethylsilyl)-1-propyne] (PTMSP) is a perspective membrane material for two inherently different applications: (i) organic solvent nanofiltration (OSN), when a high solvent flux through the membrane

Optical properties of poly-(1-trimethylsilyl-1-propyne) in solvents with different refractive indices and optical anisotropies have been studied by the dynamic birefringence method. An optical shape-effect has been detected in solvents characterized

The treatment of waste water streams containing low amounts of VOC's is still quite difficult to handle. In particular, for small or medium flow rates this problem remains most often unsolved by conventional techniques orcannot be treated directly at

In contrast to common glassy polymers, poly(1-trimethylsilyl-1-propyne) (PTMSP), a high free volume glassy polymer, shows a preferable permeation of large condensable organic vapors in comparison to permanent gases. In order to investigate this pheno
