Abstract

The present invention provides a fluorinated alkylalkoxylate of Formula (1) R f —(CH 2 CF 2 ) n (CH 2 ) m —(CH 2 CH 2 O) p —XH  (1) wherein R f is a linear or branched perfluoroalkyl group of 1 to 6 carbon atoms; n is an integer from 1 to 4; X is O; m is an integer from 1 to 6; and p is an integer from 1 to about 40; and a method of altering the surface behavior of a liquid with the fluorinated alkylalkoxylate of Formula (1).

Claims (24)

1. A compound of Formula 1:

R f —(CH 2 CF 2 ) n (CH 2 ) m —(OCH 2 CH 2 ) p —XH  (1)

wherein

R f is a linear or branched perfluoroalkyl group of 1 to 6 carbon atoms;

n is an integer from 1 to 4;

X is O;

m is an integer from 1 to 6;

and

p is an integer from 1 to about 40.

2. The compound of claim 1 wherein R f is C 4 or C 6 .

3. The compound of claim 1 , wherein m is an integer from 1 to 4.

4. The compound of claim 1 , wherein p is an integer from 1 to about 30.

5. A method of altering the surface behavior of a liquid comprising adding to the liquid a compound of a Formula (1):

R f —(CH 2 CF 2 ) n (CH 2 ) m —(OCH 2 CH 2 ) p —XH  (1)

wherein

R f is a linear or branched perfluoroalkyl group of 1 to 6 carbon atoms;

n is an integer from 1 to 4;

X is O;

m is an integer from 1 to 6;

and

p is an integer from 1 to about 40.

6. The method of claim 5 wherein m is an integer from 1 to 4 and p is an integer from 4 to about 13.

7. The method of claim 5 wherein the surface behavior is selected from the group consisting of wetting, antistatic, antifoaming, penetration, spreading, leveling, flowing, emulsifying, dispersing, repelling, releasing, lubricating, etching, bonding, and stabilizing.

8. The method of claim 5 wherein the liquid is a coating composition, battery composition, fire-fighting agent, latex, polymer, floor finish, ink, emulsifying agent, foaming agent, release agent, repellency agent, flow modifier, film evaporation inhibitor, wetting agent, penetrating agent, cleaner, grinding agent, electroplating agent, corrosion inhibitor, etchant solution, soldering agent, dispersion aid, microbial agent, pulping aid, rinsing aid, polishing agent, personal care composition, drying agent, antistatic agent, floor finish, or bonding agent.
