ABSTRACT:
Bisperfluoroalkyl-substituted diols containing sulfide, sulfone or polysulfide linkages and a method for making them are described. These diols can react with isocyanates to form urethanes; diisocyanates to form polyurethanes; chloroformates to form carbonates; with carboxylic, sulfuric or phosphoric acids or derivatives to form carboxylate esters, sulfate esters, phosphate esters respectively. These diol compounds and their derivatives are useful for imparting oil and water repellency to substrates such as glass, wood, paper, leather, wool, cotton, polyester and other substrates.
