Claims16
An onium-functionalized siloxane having the general Formula (X)
- wherein:
- R1, R2, R3, R4, R5 and R6 may be the same or different and each is independently selected from a hydrogen atom or a linear, branched or cyclic hydrocarbon residue having 1 to 20 carbon atoms which may contain at least one heteroatom;
- A is a heteroatom;
- Z is selected from a linear, branched or cyclic hydrocarbon residue having 2 to 60 carbon atoms which may contain at least one heteroatom;
- Y is an onium group;
- X is selected from halogen atoms, pseudohalogens, or anions selected from Tf2N, BF4 or PF6;
- in Formula (X) n1 is an integer from 1 to 1000, n2 is an integer from 0 to 100, and p is an integer from 0 to 1000, wherein n2 or p is an integer greater than 1.

A method for preparing the onium-functionalized siloxane having the general Formula (X) or (X-A),
- wherein the method comprises:
- (i) providing a siloxane having the general Formula (I) or (I-A)
- wherein:
- R1, R2, R3, R4, R5 and R6 may be the same or different and each is independently selected from a hydrogen atom or a linear, branched or cyclic hydrocarbon residue having 1 to 20 carbon atoms which may contain at least one heteroatom;

- Z is selected from a linear, branched or cyclic hydrocarbon residue having 2 to 60 carbon atoms which may contain at least one heteroatom;
- Y is an onium group;
- X is selected from halogen atoms, pseudohalogens, or anions selected from Tf2N, BF4 or PF6;
- in Formula (X) and Formula (I), n1 is an integer from 1 to 1000, n2 is an integer from 0 to 100, and p is an integer from 0 to 1000, wherein n2 or p is an integer greater than 1;
- in Formula (X-A) and Formula (1-A), n1 is an integer from 1 to 100, n2 is an integer from 0 to 10, and p is an integer from 0 to 100, wherein the sum p+n1+n2 is equal to or higher than 3;
- and
- (ii) nucleophilic substitution of X on the siloxane of Formula (1) or (II-A) by a nucleophile containing at least one atom selected from the 15th or 16th group of the periodic table.
