Abstract: FLUORINATED POLYMERS AND COPOLYERS ARE OBTAINED BY REACTING TOLUENE DIISOCYANTE WITH FLUORINATED ALKANOLS, OPTIONALLY IN ADMIXTURE WITH FLUORINE-FREE ALKANOLS, AND ETHYLENE IMINE AND POLYMERIZING THE SO-OBTAINED ETHYLENE IMINE UREAS IN THE PRESENCE OF BORON TRIFLUORIDE. THE POLYMERS AND COPOLYMERS ARE WATER- AND OIL-REPELLENT AGENTS FOR FIBROUS MATERIALS, ESPECIALLY TEXTILES.
