ORGANISKT POLYMERMATERIAL OCH JONBYTARMEMBRAN FRAMSTAELLT DAERAV.

摘要

A homogeneous blend which comprises from 5 to 95% by weight, preferably at least 40% by weight, of at least one fluoropolymer which contains ion-exchange groups and from 95% to 5% by weight, preferably not more than 60% by weight, of at least one fluoropolymer which is substantially free of ion-exchange groups. The homogeneous blend may be produced by melt processing the fluoropolymers and a major application of the homogeneous blend is as an ion-exchange membrane. The presence of the fluoropolymer substantially free of ion-exchange groups in the homogeneous blend leads to an improvement in physical and mechanical properties of the ion-exchange membrane, and to an improved performance of the membrane in electrolysis.
