| Popis: | The influence of additives of polyethylene glycol with M-400 and polyvinyl pyrrolidone K-90 to polysulfone spinning solutions on the transport properties of membranes is studied. It is shown that the use of compounded porofors (low-molecular PEG-PVP) for the obtaining of polysulfone membranes allows for the significant enhancing of their hydraulic permeability with the simultaneous enhancing of rejection power. Differences in the morphology of membranes with the use of individual and compounded porofors are shown. |
