| 摘要 |
The invention relates to a covalently cross-linked composite and a covalently cross-linked composite polymer membrane consisting of at least one polymer and tectosilicates and/or phyllosilicates. Said tectosilicates and/or phyllosilicates can be both functionalised or non-functionalised. The polymers are characterised in that they can carry 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 exchanger groups SO2M and/or POM2 and/or COM, and b) sulfinate groups SO2Me; and can be covalently cross-linked by means of the following organic compounds: a) difunctional, trifunctional or oligofunctional haloalkanes or haloaromatics which have been reacted with the sulfinate 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-; CH2-arylene-CH2-, x=3-12): polymer-SO2-Y-SO2-polymer; and/or b) compounds containing the groups Hal-(CH2)x-NHR, one side (Hal-) thereof having been reacted with sulfinate groups SO2Me, and the other side (-NHR) having been reacted with SO2Me groups, whereby the following cross-linking bridges are present in the polymer/in the polymer mixture/in the polymer membrane: polymer-SO2-(CH2)x-NR-SO2-polymer; and/or c) compounds containing the groups NHR-(CH2)x-NHR which have been reacted with the SO2Me groups, whereby the following cross-linking bridges are present in the polymer/in the polymer mixture/in the polymer membrane: polymer-SO2-NR-(CH2)x-NR-SO2-polymer. |
