Condensation products of aldehydes and fluoraliphatic phenols are substantive to wool, synthetic polyamides, leather and skin, the compositions preferably being extended with a suitable pharmaceutical medium. The condensation products are useful for the preparation of compositions that render such materials oil and water repellent.
Fluoroaliphatic phenols are prepared by reacting an olefinic phenol with a perfluoroalkyl sulfonyl chloride, bromide, or fluoride in the presence of a free radical catalyst at a temperature of from about 100.degree.-150.degree. C. The fluoroaliphatic phenols are useful in the preparation of condensation products with aldehydes which products are substantive to the skin and render the skin or similar materials repellent to aqueous and oily materials.
