Self-standing dense membranes from hyperbranched copolyimides based on (hexafluoroisopropylidene)diphthalic anhydride (6FDA), 1,3,5-tris(4-aminophenoxy)benzene (TAPOB) and 4,4´-(hexafluoroisopropylidene)dianiline (6FpDA) were successfully prepared and characterized for physicochemical properties. Th

An alternative method using established polymer processing and membrane formation processes to prepare hydrophilic membranes based on acid modified polyolefins is introduced. This process includes blend formation by reactive extrusion of functionalized polyolefins (polypropylene; PP) and a hydrophil

A novel method for measuring local permeabilities of gas or vapor in polymers was proposed and developed. The method utilizes a thin reactive layer of potassium prepared on one side of the examined polymer film. Molecules of an appropriate gas (oxygen, water vapor) diffusing through the film corrode
