Flexible microporous cellulosic membranes and methods of formation and use thereof

Microfiltration membranes are described comprising 10% to 50% cyanoethylated polysaccharide ether polymers blended with 50% to 90% polymers of cellulose nitrate, cellulose acetate or mixtures of the two. These membranes are flexible and strong and can be readily pleated for use in cartridge filters...

description	Microfiltration membranes are described comprising 10% to 50% cyanoethylated polysaccharide ether polymers blended with 50% to 90% polymers of cellulose nitrate, cellulose acetate or mixtures of the two. These membranes are flexible and strong and can be readily pleated for use in cartridge filters as well as used flat in conventional single- or multi-plate holders. They are also more thermally stable than conventional "mixed ester" (cellulose nitrate/cellulose acetate) membranes.
