ABSTRACT:
Fluorochemical compositions comprising fluorinated compounds, wherein the fluorinated compound comprises fluorochemical oligomeric portion, an organic moiety, and a group that can impart soft hand, stain release, water repellency, or a durable property when the compound is applied to a fibrous substrate, wherein the fluorochemical oligomeric portion is bonded to the organic moiety through an isocyanate-derived linking group. Also disclosed are fluorochemical compositions in the form of fluorochemical liquid dispersions and methods for preparing substrates treated with such compositions. Substrates so treated exhibit particularly durable and abrasion-resistant oil and water repellent properties. Intermediates in the preparation of the fluorochemical compositions are also disclosed. Some of the intermediates are useful as emulsifiers in fluorochemical liquid dispersions.
