    Abstract: Perfluoroalkylthio glycols and esters thereof can be prepared by the free-radical catalyzed addition of a perfluoroalkylthiol to an acetylenic alcohol or ester thereof. The compounds obtained are useful intermediates for the synthesis of fluorochemicals with low free surface energies having oil and water repellent properties. In one embodiment, a perfluoroalkylthio glycol can be reacted with a diisocyanate to obtain a polyurethane containing perfluoroalkylthio groups, which polyurethanes are useful as coatings to provide oil and water repellance to textiles and as additives to plastics to provide mold-release and other desirable properties.
