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.
Claims21
A fluorochemical oligomeric compound comprising:
- (i) an oligomeric portion having both fluoroaliphatic and fluorine-free aliphatic pendent groups;
- (ii) an aliphatic moiety;
- and
- (iii) a linking group which links the oligomeric portion to the aliphatic moiety, wherein at least one of said fluorine-free aliphatic pendent groups or said aliphatic moiety has 22 or more carbon atoms.
