IMPROVING METHOD FOR FFCONTAINING CATION EXCHANGE MEMBRANE |
| 摘要 |
<p>PURPOSE:To lower the density of ion exchange groups in the surface layer alone of a F-contg. cation exchange membrane having sulfonyl halide groups and thus decrease the OH ion permeability by attaching a radical reaction initiator to the surface of the membrane and heating the membrane to a temp. above the decomposition point of the initiator.</p> |
