Abstract

A copolymer of polyvinyl alcohol and trifluoro acetaldehyde derivatized to have a substituent that contains fluorine. Such compositions are useful in compatibilizing fluorinated molecules that are to be blended into liquid materials or systems, as well as materials and systems that may be aerosolizable or foamable liquids.

Claims (8)

1. A composition, comprising: a copolymer of polyvinyl alcohol and trifluoro acetaldehyde.

2. The composition of claim 1 , wherein the composition further comprises an F-POSS material.

3. A composition comprising: poly (4,6-methylenyl-1,3-dioxan-2-trifluormethyl)-vinylalcohol.

4. The composition of claim 2 , wherein the F-POSS material comprises 6/2 F-POSS.

5. The composition of claim 2 , wherein the ratio of copolymer to F-POSS in the composition is 1:1.

6. The composition of claim 2 , further comprising a polyurethane paint system.

7. The composition of claim 6 , wherein the polyurethane paint system comprises 90% of the composition.

8. A composition according to claim 1 , wherein the copolymer of polyvinyl alcohol and trifluoro acetaldehyde has the formula:
