abstract |
The invention relates to a hydrophilized, microporous membrane and process for its production. The aim of the invention is to produce a hydrophilized, microporous membrane made of PTFE.n n n According to the invention, the hydrophilized, microporous membrane consists of unmodified PTFE and 2.5 to 25% by mass of highly functionalized PTFE as a largely polymer-identical hydrophilizing agent. The highly functionalized PTFE is obtained by irradiation and optionally by adding sulfites and carbonates.n n n The invention furthermore relates to processes for producing the membranes. |
