| 摘要 |
<p>This invention relates to fluorochemical compositions, their preparation and their use as water-and oil-repellents, and substrates treated therewith. The fluorochemical composition comprises a mixture of fluorochemical compounds and/or polymers, each component having at least two fluoroaliphatic groups and a large hydrocarbon moiety such as derived from dimer acids, and the polymer having at least one fluoroaliphatic group and a plurality of said hydrocarbon moiety.</p> |
