## Abstract

The invention relates to novel compounds of the formula I, II; III or IV wherein the general symbols are as defined in claim 1. These compounds are useful as surface modifiers for polymers in order to improve resistance to fog formation or water and oil repellency.

## Claims

### Claim 1

A composition comprising
a) a polymer or a mixture of polymers and
b) as additive for surface modification, at least one compound of the formula I or II or sorbitane 5-phenyl-2,4-pentadienoate, or a mixture thereof;
sorbitane 5-phenyl-2,4-pentadienoate
wherein
A1 is a polyoxyalkylene ether residue of the formula —O—[—CH2—CH2—O]q—CH2—CH2—OR2, wherein q is from 4 to 30 and R2 is C1-C20alkyl,; —O—CH2—CH2—(CF2)j—CF3, wherein j is from 3 to 8; a glycerol residue or a sorbitane residue,
X is —C(O)A1,
R is hydrogen,
W is hydrogen or C1-C20alkoxy and
n is 1.

### Claim 2 (depends on 1)

A composition according to claim 1, wherein the polymer is a polyolefin, a polyester or a polycarbonate.

### Claim 3 (depends on 1)

A composition according to claim 1, wherein component (b) is present in an amount of from 0.01 to 10% based on the weight of component (a).

### Claim 4 (depends on 1)

A composition according to claim 1, wherein the polymer or mixture of polymers is in the form of a film or a sheet.

### Claim 5

A process for modifying the surface of polymers in order to improve resistance to fog formation or water and oil repellency, which comprises incorporating therein or applying thereto at least a compound of the formula I or II or sorbitane 5-phenyl-2,4-pentadienoate;
sorbitane 5-phenyl-2,4-pentadienoate
wherein
A1 is a polyoxyalkylene ether residue of the formula —O—[—CH2—CH2—O]q—CH2—CH2—OR2, wherein q is from 4 to 30 and R2 is C1-C20alkyl,; —O—CH2—CH2—(CF2)j—CF3, wherein j is from 3 to 8; a glycerol residue or a sorbitane residue,
X is —C(O)A1,
R is hydrogen,
W is hydrogen or C1-C20alkoxy and
n is 1.
