摘要：
Polyethers (A), whose main chain essentially consists of repeating units of the formulae (1) and (2) in alternating order, are useful as an additive to a porous polymer membrane, or as the main polymer constituent of a porous polymer membrane, for stabilizing said membrane against detrimental effects of oxidizing agents and/or for improving the stability of a filtration module comprising said membrane against detrimental effects of oxidizing agents.
