Title:

POLYMERS AND POLYMER MEMBRANES COVALENTLY CROSS-LINKED BY SULPHINATE ALKYLATION

Document Type and Number:

WIPO Patent Application WO2002000773

Kind Code:

A9

Abstract:

The invention relates to a covalently cross-linked polymer or polymer membrane consisting of one or more polymers, which can bear the following functional groups (M=Hal (F, Cl, Br, I), OR, NR2; R=alkyl, hydroxyalkyl, aryl; (Me=H, Li, Na, K, Cs, or other metal cations or ammonium ions); a) precursors of cation exchange groups: SO2M and/or POM2 and/or COM b) sulphinate groups SO2Me and which can be covalently cross-linked using the following organic compounds: a) di, tri or oligofunctional haloalkanes or haloaromatics, which have been reacted with sulphinate groups SO2Me, whereby the following cross-linking bridges are present in the polymer/in the polymer blend/in the polymer membrane (Y=cross-linking bridges, X=Hal (F, Cl, Br, I), OR, Y=(CH2)x-; -arylene-; -(CH2)x-arylene-; CH2arylene-CH2-, x=3-12): polymer-SO2Y-SO2-polymer and/or b) compounds containing the following groups: Hal-(CH2)x-NHR, one side of which (Hal-) has been reacted with sulphinate groups SO2ME and the other side (-NHR) with SO2M groups, whereby the following cross-linking bridges are present in the polymer/in the polymer blend/in the polymer membrane: polymer-SO2-(CH2)x-NR-SO2-polymer and/or c) compounds containing the following groups: NHR-(CH2)x)-NHR, which have been reacted with sulphinate groups SO2Me, whereby the following cross-linking bridges are present in the polymer/in the polymer blend/in the polymer membrane: polymer-SO2-NR-(CH2)x-NR-SO2-polymer.
