Abstract: 2-PERFLUOROALKYL ETHANOLS ARE OBTAINED BY REACTING 2PERFLUORO-ALKYL ETHYLIODIDES WITH AT LEAST THE TWO-FOLD MOLAR AMOUNT OF NITRIC ACID OF ABOUT 70 TO 98% STRENGTH AND HYDROGENATING THE INTERMEDIATES,WHICH ARE THE NITRATES OF THE DESIRED ETHANOLS. THE PRODUCTS ARE USEFUL AS STARTING MATERIALS FOR THE PRODUCTION OF HYDROPHOBIC AND OLEOPHOBIC TEXTILE FINISHING AGENTS, E.G. THE POLYMER ACRYLATES AND METHACRYLATES OF SAID 2-PERFLUOROALKYL-ETHANOLS.

Abstract: POLYADDUCTS ARE OBTAINED WHEN TREATING METHANES HAVING ETHYLENE-IMINE RINGS AND A POLYETHER CHAIN OR A FLUOROALKYL CHAIN WITH ACIDIC COMPOUNDS. THE POLYADDUCTS ARE TEXTILE FINISHING AGENTS RENDERING TEXTILES HYDROPHOBIC AND OLEOPHOBIC AND ACHIEVE THE SO-CALLED SOIL-RELEASE EFFECT.

Abstract: ADDUCTS FROM FLUOROALKANOLS, TOLUENE DIISOCYANATES AND POLYETHYLENE GLYCOLS ARE USEFUL FOR RENDERING TEXTILES OIL-AND WATER REPELLENT AND ACHIEVE THE "SOIL RELEASE EFFECT." FURTHERMORE, THEY ARE DISPERSING AGENTS FOR OILAND WATER REPELLENT POLYMERS MADE OF ADDUCTS FROM SAID FLUOROALKANOLS, TOLUENE DIISOCYANATES AND EHTYLENE IMINE.
