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.
Claims5
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.
