Alkylated fluorochemical oligomers and use thereof

摘要

This invention provides fluorochemical compounds comprising: a fluorochemical oligomeric portion comprising an aliphatic backbone with a plurality of pendant fluoroaliphatic groups, each fluoroaliphatic group having a fully fluorinated terminal group and each independently linked to a carbon atom of the aliphatic backbone through an organic linking group; an aliphatic moiety; and a linking group which links the fluorochemical oligomeric portion to the aliphatic moiety. The fluorochemical compounds are useful as topical treatments for fibrous substrates such as textiles and fabrics, and as polymer melt additives to provide desirable oil-, water and stain repellency to shaped articles such as fibers.
