Abstract
Polyacrylonitrile capillary membrane (PAN membrane), with an average pore size of less than 10 nm, a narrow pore size distribution characterised by sigma -values of less than 0.3, and a pore density of more than 109 pores/cm2 in the active separation layer. Also claimed is a process for the production of PAN capillary membrane with a comonomer content of less than 1 wt%. USE - Used as an osmosis membrane, especially in capillary osmometers (claimed). ADVANTAGE - An improved capillary membrane with a small pore size, a narrow pore size distribution and a high pore density, combined with good wettability and good stability in typical membrane osmometry solvents, e.g. water, ether, toluene, THF, dioxan, acetone, trichloroethylene.
