Abstract

A silicon-containing polymer is represented by the general formula: (I) wherein A, Q, Z, x, and y are as defined in the specification, and I is iodine. Group Q includes a hydrolyzable silane group and group A is fluorinated. A method of making the silicon-containing polymer is also disclosed.

First claim

What is claimed is:

1. A silicon-containing polymer represented by the general formula:
A-[Q] x -[Z] y —I

wherein:
A represents a monovalent group represented by the formula
R f 2 R f 1 R h —

wherein
R h represents a covalent bond or an alkylene group having from 1 to 18 carbon atoms,
R f 1 represents a covalent bond or a divalent group selected from the group consisting of —(CF 2 O) a —, —(CF 2 CF 2 O) b —, —(CF 2 CF 2 CF 2 O) c —, —(CF 2 CF 2 CF 2 CF 2 O) d —, —(CF 2 CF(CF 3 )O) e —, and combinations thereof, wherein a, b, c, d, and e represent integers in the range of from 0 to 130, and wherein 1≤a+b+c+d+e≤130, and
R f 2 represents a perfluoroalkyl or perfluoroalkoxy group having from 1 to 8 carbon atoms;

each Q independently represents at least one divalent monomeric unit represented by the formula

wherein
R 1 represents H or methyl,
L 1 represents a covalent bond or a divalent aliphatic group having from 1 to 10 carbon atoms,
each Y 1 independently represents a hydrocarbyl group having from 1 to 6 carbon atoms,
each Y 2 independently represents a hydrolyzable group, and
g is 0, 1, or 2; and

each Z independently represents a divalent residue of a non-halogenated free-radically polymerizable ethylenically-unsaturated monomer having from 2 to 18 carbons,
wherein x represents an integer greater than or equal to 3, and y represents an integer greater than or equal to zero.

2. The silicon-containing polymer of claim 1 , wherein R h has from 1 to 4 carbon atoms.

3. The silicon-containing polymer of claim 1 , wherein R f 1 represents a covalent bond.

4. The silicon-containing polymer of claim 1 , wherein R f 2 has from 1 to 4 carbon atoms.

5. The silicon-containing polymer of claim 1 , wherein L 1 has from 1 to 4 carbon atoms.

6. The silicon-containing polymer of claim 1 , wherein each Z independently represents a divalent residue of a non-halogenated free-radically polymerizable ethylenically-unsaturated monomer having from 2 to 8 carbons.
