Patent ID: 8887927

Claim:
A self-supporting polymeric membrane, wherein self-supporting polymeric membrane is formed from a dynamic polymer formed from repeating units of formula (I) below: in which: D represents a subunit of formula (I D ) below: in which: x is an integer ranging from 10 to 20; p=0 or 1; and * is the point of attachment of D to G via an imine bond; G represents a subunit of formula (I G ) below: in which: R 1 represents a hydrogen atom or an alkyl radical containing from 1 to 4 carbon atoms, Y represents a nitrogen atom or C—OH, # is the point of attachment of G to D via an imine bond; it being understood that at least 50% by number of said subunits of formula (I G ) present in said polymer form a complex with a transition metal ion.
