Patent ID: 8748556

Claim:
A self-supporting polymeric membrane, wherein said 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; 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—R 2 with R 2 =H or OH; # is the point of attachment of G to T via a reversible imine bond; T represents a subunit of formula (I T ) below: in which: R 3 represents a hydrogen atom or an alkyl radical containing from 1 to 6 carbon atoms, R 4 and R 5 , which may be identical or different, represent a hydrogen atom or an alkyl radical containing from 1 to 6 carbon atoms, n is an integer ranging from 1 to 20, p is an integer ranging from 1 to 20, # represents the point of attachment of T to G; it being understood that said subunits T represent from 20 mol % to 45 mol % relative to the number of moles of subunits G constituting said dynamic polymer.
