Polyfluoroureas
Abstract
Abstract HYDROXYMETHYLATED DERIVATES OF POLYFLUOROALKYLUREAS ARE USEFUL FOR IMPARTING OIL, WATER AND CREASE RESISTANCE TO FIBROUS SUBSTRATES. THE POLYFLUOROALKYLUREAS HAVE THE FORMULA: RF-Y-N(-R1)-CO-N(-R2)-R WHEREIN RF IS N-PERFLUOROALKYL GROUPPF4-6 CARBON ATOMS; Y IS AN ALKYLENE BRIDGE OPTICALLY INTERUPTED WITH --O--, --S--, --SO--, --SO2--, --SO2NR''--, --CONR''--, ==C(O)0--, AND --NR''-- WHEREIN R7 REPRESENTS HYDROGEN,LOWER ALKYL AND -UREIDO; R1 AND R2 ARE EACH HYDROGEN, LOWER ALKYL OR TAKEN TOGETHER CAN COMPLETE AN IMIDOZLIDONE OR PYRIMIDONE RING AND R IS HYDROGEN, LOWER ALKYL, OR RF--Y--, IT BEING PROVIDED THAT AT LEAST ONE UREA NITROGEN ATOM HAS HYDROGEN BONDED THERETO AND IT BEING FURTHER PROVIDED THAT THE NUMBER OF CARBON ATOMS IN Y IS 2-12 FOR THE NON-INTERRUPTED BRIDGE AND 2-60 FOR THE INTERRUPTED BRIDGE.
