This paper describes the reaction of the highly reactive -NC0 group as present in diisocyanate with the basic -OH group as present in cellulose acetate in a mixture of dichloromethane and t-butyl alcohol, thereby producing minimally crosslinked cellulose acetate, bearing urethane groups and conseque

The variation in flux and rejection of replicate cellulose acetate membranes is measured within a membrane sheet as well as between membranes. Although

Using models of dead-end filtration theory, the kinetics of forming dynamic layers of sulfate lignin (SL) and sodium carboxymethylcellulose ( Na-CMC) onto CA membranes during cross-flow filtration of dilute solutions of polymers was studied. It was found for both polymers (compact SL and linear Na-C
In the present work, N,N-dimethylformamide was chosen as a cosolvent of cellulose acetate (CA) and polyacrylonitrile (PAN). The blend solution showed appropriate viscosity, good membrane-forming property and relative stability.
