Abstract: The presented study provides a possibility to create ultrafiltration (UF), polyacrylonitrile(PAN)/butadiene-acrylonitrile elastomer (BNR)/N,N-dimethylformamide (DMF) membranes. Influence of different concentrations of the elastomer on the formation of a more porous structure was studied and compared with that observed using membranes made of polyacrylonitrile. Specific influence of copper ions in a solution of polymers on the formation of an asymmetric selective layer was also monitored. The study was conducted to prepare membranes with high efficiency in emulsion and colloidal systems separation.

Keywords: ultrafiltration – polyacrylonitrile – modification membranes – asymmetric membranes
