Wet spinning of asymmetric hollow polysulfone fibres by the double spinning bath method

The possibility of fabricating an asymmetric hollow fibre from polysulfone in a one-stage process with the double spinning bath method was demonstrated. A correlation was established between the quality of the selective layer and the value of the diffusion coefficient of the solvent in the precipitant.Russian Institute of Chemical Technology, Moscow.
