WATER- AND OIL-REPELLENCY IMPARTING ESTER OLIGOMERS COMPRISING PERFLUOROALKYL MOIETIES

摘要

Fluorochemical ester compositions comprising one or more compounds or oligomers having at least one long chain fluorine-containing repeatable unit and at least one fluorine-containing terminal group are described. The compositions are useful as coatings. The fluorochemical compositions impart oil and water repellency to the substrate. In other aspects, this invention relates to processes for imparting oil and water repellency characteristics to substrates and articles.
