Abstract

A polyarylene ether copolymer comprising i) at least one block comprising in polymerized form A) isosorbide, isomannide, isoidide or a mixture thereof and B) at least one unit comprising at least one difunctional compound comprising at least one dichlorodiaryl sulfone, a dichlorodiaryl ketone or a mixture thereof and ii) at least one block comprising in polymerized form C) at least one polyalkylene oxide, 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 copolymer comprising
i) at least one block comprising in polymerized form
A) isosorbide, isomannide, isoidide or a mixture thereof and
B) at least one unit comprising at least one difunctional compound comprising at least one dichlorodiaryl sulfone, a dichlorodiaryl ketone or a mixture thereof and

ii) at least one block comprising in polymerized form
C) at least one polyalkylene oxide.

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

3. The polyarylene ether copolymer according to claim 1 , comprising
C) at least one polyethylene oxide.

4. The polyarylene ether copolymer according to claim 1 ,
wherein the polyalkylene oxide has a number average weight of from 200 to 20 000 g/mol, determined by potentiometric titration using potassium hydroxide solution.

5. The polyarylene ether copolymer according to claim 1 , comprising in polymerized form
E) at least one tri- or higher functional monomer.

6. The polyarylene ether copolymer according to claim 5 , comprising
E) 1,1,1-trishydroxyphenyl ethane.

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

where the definitions of the symbols Z, r, t, q, Q, T, Y, Ar and Arl 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—, —SO2-, S—O, C—O, —N═N—, and —CRaRb—, where Ra and Rb 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 —SO2- or —CO—,
Z: a group derived from isosorbide, isomannide, or 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 copolymer comprising reacting
a) isosorbide, isomannide, isoidide or a mixture thereof and
b) at least one difunctional compound comprising a dichlorodiaryl sulfone, a dichloodiaryl ketone or a mixture thereof with
c) at least one polyalkylene oxide.

9. The process according to claim 8 comprising reacting components a), b), and c) in the presence of at least one polar aprotic solvent in the absence of an azeotrope forming compound.

10. A method for preparation of coatings, films, fibers, foams, membranes or molded articles comprising utilizing a polyarylene ether copolymer according to claim 1 .

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

12. A dope solution for the manufacture of membranes comprising at least one polyarylene ether copolymer according to claim 1 .

13. A fiber comprising at least one polyarylene ether copolymer according to claim 1 .

14. A membrane comprising at least one polyarylene ether copolymer according to claim 1 .

15. An article comprising at least one membrane according to claim 14 .

16. A method for contacting water, a body fluid, or a liquid in food production comprising utilizing the membrane according to claim 14 .

17. A method for separating gases comprising utilizing the membrane according to claim 14 .
