Abstract

A polyarylene ether comprising in polymerized form A) at least one tri- or higher functional compound and B) isosorbide. isomannide, isoidide or a mixture thereof, wherein the polyarylene ether is a polyarylene ether sulfone or a polyarylene ether ketone, ¢ process for its preparation and its use in the preparation of a coating, film, fiber, foam, membrane or molded article.

First claim

The invention claimed is:

1. A polyarylene ether comprising in polymerized form
A) at least one tri- or higher functional compound and
B) isosorbide, isomannide, isoidide or a mixture thereof,
wherein the polyarylene ether is a polyarylene ether sulfone or a polyarylene ether ketone.

2. The polyarylene ether according to claim 1 , comprising
A) at least one trifunctional compound.

3. The polyarylene ether according to claim 1 , comprising
A) at least one triol.

4. The polyarylene ether according to claim 1 , comprising
A) 1,1,1-trishydroxyphenyl ethane.

5. The polyarylene ether according to claim 1 , comprising
B) isosorbide.

6. The polyarylene ether according to claim 1 , comprising diol
C1) least one compound having two hydroxy groups and which is not compound B.

7. The polyarylene ether according to claim 1 , comprising
A) 0.5 to 5 mol %, based on the total amount of compounds A and B and diol C1 comprised in the polyarylene ether at least one tri- or higher functional compound.

8. The polyarylene ether according to claim 1 , comprising at least one unit of the general formula II

where the definitions of the symbols t, q, Q, T, Y, Ar and Ar 1 are as follows:
t, q: independently of one another 0, 1, 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 C 1 -C 12 -alkyl, C 1 -C 12 -alkoxy, or C 6 -C 18 -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, and
Ar and Ar 1 : independently of one another an arylene group having from 6 to 18 carbon atoms.

9. A process for the preparation of a polyarylene ether comprising reacting
a) at least one tri- or higher functional compound and
b) isosorbide, isomannide, isoidide or a mixture thereof with
c) a difunctional compound comprising at least one dichlorodiaryl sulfone, a dichlorodiarylketone or a mixture thereof.

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

11. A fiber comprising a polyarylene ether according to claim 1 .

12. A membrane comprising the polyarylene ether according to claim 1 .

13. An article comprising the membrane according to claim 12 .

14. The article according to claim 13 in contact with water, a body fluid or a liquid in food production.
