Onium-Functionalized Siloxanes

An onium-functionalized siloxane having the general Formula (X) or (X-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;
• 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;
• and
• in Formula (X-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.
