Abstract
The present invention provides a novel fluorochemical oligomer, and polymer composition comprising the fluorochemical oligomeric compound and a thermoplastic or thermoset polymer. The polymer composition is useful in preparing shaped articles such as fibers and films which have desirable oil- and water repellency properties.
Claims20
A fluorochemical oligomer having the structure:
- wherein the sum of a+b is an number such that the compound is oligomeric;
- R1 is hydrogen, halogen, or straight chain or branched chain alkyl containing 1 to about 4 carbon atoms;
- each R2 is independently hydrogen or straight chain or branched chain alkyl containing 1 to about 4 carbon atoms;
- Q and Q′ are each independently a covalent bond or an organic linking group,
- Rf is a fluoroaliphatic group that comprises a fully fluorinated terminal group;
- Rh is a fluorine-free aliphatic group;
- and
- X is a hydrogen atom or a group derived from a free radical initiator;
- and
- L is a non-polymeric linking group.
