Polyfluoroalkylthio alcohols, esters and useful compositions therefrom

摘要

Polyfluoroalkylthio alcohols and esters thereof are disclosed with utility as intermediates for the synthesis of fluorochemicals with low free surface energies having oil and water repellent properties. The novel alcohols and esters are obtained by a free radical catalyzed addition of polyfluoroalkylthiols to acetylenic alcohols or esters thereof. The alcohols are employed in preparation of fluorine containing polyurethanes which are useful as finishes to provide oil and water repellency to textiles and as additives to plastics to provide mold release and other desirable properties.
