Abstract

A polyarylene ether sulfone comprising in polymerized form A) isosorbide, isomannide, isoidide or a mixture thereof and B) at least one nonsulfonated dihalodiaryl! sulfone (compound B) and C) at least one sulfonated dihalodiaryl sulfone (compound C), a process for its preparation and its use in the preparation of coatings, films, fibers, foams, membranes or molded articles.

First claim

The invention claimed is:

1. A polyarylene ether sulfone comprising in polymerized form
A) isosorbide, isomannide, isoidide or a mixture thereof and
B) at least one at least one nonsulfonated dihalodiaryl sulfone (compound B) and
C) at least one sulfonated dihalodiaryl sulfone (compound C) and
D) at least one tri- or higher functional monomer.

2. The polyarylene ether sulfone according to claim 1 , comprising
A) isosorbide.

3. The polyarylene ether sulfone according to claim 1 , comprising
from 20 to 99 mol-% of compound B and
from 1 to 20 mol-% of compound C,
based on the sum of the mol-% of compounds B and C.

4. The polyarylene ether sulfone according claim 1 wherein compound C is 4,4′-dichlorodiphenylsulfone-3,3′-disulfonic acid or 4,4′-dichlorodiphenylsulfone-3,3′-disulfonic acid disodium salt or a mixture thereof.

5. The polyarylene ether sulfone according to claim 1 , comprising
E) at least one triol.

6. The polyarylene ether sulfone according to claim 1 , comprising
E) 1,1,1-trishydroxyphenyl ethane.

7. The polyarylene ether sulfone according to claim 1 , comprising in polymerized form at least one unit of the general formula (I)

where the definitions of the symbols t, q, Q, T, Y, Ar and Ar 1 are as follows:
r: 0, or 1
t, q: independently of one another 0, or 1, or 2, or 3,
Q, T, Y: independently of one another in each case a chemical bond or group selected from —O—, —S—, —SO 2 —, S═O, C═O, —N═N—, and —CR a R b —, where R a and R b independently of one another are in each case a hydrogen atom or a C1 to C12-alkyl, C1 to C12-alkoxy, C3 to C12-cycloalkyl, or C6 to C18-aryl group, and where at least one of Q, T, and Y is —SO 2 — or —CO—,
Z: a group derived from isosorbide, isomannide, isoidide
Ar and Ar 1 : independently of one another an arylene group having from 6 to 18 carbon atoms.

8. A process for the preparation of a polyarylene ether sulfone comprising reacting
a) isosorbide, isomannide, isoidide or a mixture thereof and
b) at least one nonsulfonated dihalodiaryl sulfone,
with

c) at least one sulfonated dihalodiaryl sulfone.

9. The process according to claim 8 comprising reacting the monomers in the presence of a polar aprotic solvent in the absence of an azeotrope forming compound.

10. A method for preparing coatings, films, fibers, foams, membranes or molded articles comprising utilizing the polyarylene ether sulfone according to claim 1 .

11. The method according to claim 10 for the preparation of membranes.

12. A fiber comprising a polyarylene ether sulfone according to claim 1 .

13. A membrane comprising a polyarylene ether sulfone according to claim 1 .

14. An article comprising a membrane according to claim 13 .

15. A method comprising contacting the membrane according to claim 13 with water, a body fluid or a liquid in food production.
