Polysulfone: The Development of a Membrane for Convective Therapies

The polysulfone membrane was developed as a membrane for convective dialysis therapies at the beginning of the 1980s. The target was to produce a higher-permeable membrane on the basis of synthetic polymers, such as polysulfone. The development of a membrane with high permeability went hand in hand with a technology development that finally presented as an essential precondition for the success of the polysulfone membrane. This article describes the development phase of the polysulfone membrane using to-date unpublished extracts of the project report of the polysulfone membrane and commenting these from todays perspective.
