Oxazine and oxazoline derived c-n backbone polymers

Abstract

Abstract POLYMERS COMPRISING RECURRING UNITS OF THE STRUCTURE: -N(-CO-(CH2)Q-(C(-R4)(-R5)-C(-R2)(-R3))R-O-CF(-R)-R1)- (CH2)N- WHEREIN R AND R1, WHICH CAN BE THE SAME OR DIFFERENT, ARE PERHALOGENATED ALKYL RADICALS IN WHICH THE HALOGEN ATOMS ARE CHLORINE, OR FLUORINE, WITH AT LEAST ONE FLUORINE ATOM BEING ATTACHED TO EACH CARBON ATOM; WHEREIN R AND R1 TOGETHER CONTAIN A TOTAL OF FROM 2 TO 8 CARBON ATOMS; WHEREIN R2, R3, R4 AND R5 ARE INDEPENDENTLY CHLORINE, FLUORINE, HYDROGEN, OR PERFLUOROMETHYL WITH NOT MORE THAN ONE OF THE SUBSTITUENT GROUPS, R2, R3, R4 OR R5 IN ANY -C(-R2)(-R3)-C(-R4)(-R5)- UNIT BEING TRIFLUOROMETHYL, AND NOT MORE THAN TWO BEING CHLORINE; WHEREIN R IS 0 TO 5; WHEREIN Q IS 0 TO 11 WITH Q BEING AT LEAST 1 WHEN R=0; AND WHEREIN N AT EACH OCCURRENCE IS INDEPENDENTLY 2 OR 3; HAVE A LOW CRITICAL SURFACE ENERGY AND ARE USEFUL IN IMPARTING OIL AND WATER REPELLENCY TO FABRICS IMPREGNATED OR COATED THEREWITH. THESE POLYMERS ARE PREPARED FROM NOVEL MONOMERS OF THE STRUCTURE N<(-(CH2)N-O-C(-(CH2)Q-(C(-R4)(-R5)-C(-R2)(-R3))R-O- CF(-R)-R1)=) WHEREIN N IS 2 OR 3, AND WHEREIN R, R1, R2, R3, R4, R5, R AND Q ARE AS DEFINED ABOVE.
