| 摘要 |
Pre-swelled ion exchange membranes formed from one or more layers of fluorinated polymer having carboxylic or sulfonic acid functional groups and which polymer contains about 8 to 30% by weight of a swelling agent of the formula HO(CH2CHYO)nH where Y=H or CH3 and n=2, 3 or 4 are disclosed. Also disclosed are processes for preparing these membranes, electrochemical cells utilizing these membranes, and methods of preparing said cells for use in chloralkali processes.
