Membranes Based on Cellulose and Copolymers of Acrylonitrile Prepared from Joint Solutions

Cellulose and copolymers of acrylonitrile (PAN) are characterized by their chemical resistance to several conventional solvents. Therefore, these polymers often used obtain membranes for the recovery such In this work, first time, composite formed from highly concentrated mixed solutions based on cellulose PAN considered (the total content is 18 wt.%). For solutions, morphology rheological behavior were evaluated. It shown that resulting two-phase, depends components’ ratio system’s history. The non-monotonous change in viscosity with indicates a specific interaction N-methylmorpholine-N-oxide solutions. allows processing conditions identical those introduction into matrix promotes decrease structural order system, affecting membranes’ transport properties. membranes, it was found an increase phase, retention Remazol Orange decreases, while observed values times higher than membranes. permeability ethanol increases increasing terpolymer content.
