Abstract

Abstract FLUORINATED COMPOUNDS AND MIXTURES THEREOF OF THE GENERAL FORMULA CF3-O-(C3F6O)M-(CF2-O)N-(CF(-CF3)-O)L-CF2-C(-OH)(-R1)-CF3 WHEREIN M, N AND L MAY BE THE SAME OR DIFFERENT NUMBERS AND ARE ZERO OR A WHOLE NUMBER FROM 1 TO 100, THE SUM OF M+N+L IS ZERO OR A NUMBER BETWEEN 1 AND 100, THE RATIO OF (N+L)/(M+1) IS A NUMBER BETWEEN ZERO AND 2, C3F6 REPRESENTS THE UNIT DERIVED FROM THE OPENING OF THE DOUBLE BOND OF A MOLECULE OF HEXAFLUOROPROPYLENE, THE DIFFERENT PERFLUOROALKYLENE UNITS HAVING A RANDOM DISTRIBUTION ALONG THE POLYMER CHAIN, AND R1 IS SELECTED FROM THE GROUP CONSISTING OF -OH, -OR2, -CN, AND -NR3R4, WHEREIN R2 IS A RADICAL CONTAINING FROM 1 TO 12 CARBON ATOMS, AND IS ALKYL, ALKYLARYL, ARYL, CYCLALKYL OR IS THE CORRESPONDING HALOGEN-SUBSTITUTED RADICAL, AND R 3 AND R4 MAY BE HYDROGEN OR THE SAME OR DIFFERENT RADICALS CONTAINING FROM 1 TO 12 CARBON ATOMS AND ARE SELECTED FROM THE GROUP CONSISTING OF ALKYL, ALKYLARYL, ARYL, HALOGEN-SUBSTITUTED ARYL, CYCLOALKYL, AND THE DRIVATIVES THEREOF HAVING ONE OR MORE MOLECULES OF WATER OF HYDRATION ARE PREPARED BY REACTING CORRESPONDING PERFLUORINATED KETONES AND MIXTURES THEREOF OF THE GENERAL FORMULA CF3-O-(C3F6O)M-(CF2-O)N-(CF(-CF3)-O)L-CF2-CO-CF3 WITH A REACTANT SELECTED FROM THE GROUP CONSISTING OF WATER,PRIMARY, SECONDARY OR TERTIARY ALCOHOLS, HCN, NACN AMMONIA, PRIMARY AND SECONDARY ALIPHATIC AMINES, ANILINE, DIPHENYLAMINE, ANILINES HALO- AND ALKYL-SUBSTITUTED IN THE NUCLEUS AND DIPHENYLAMINES HALO- AND ALKYLSUBSTITUTED IN THE NUCLEUS, AT A TEMPERATURE OF FROM ABOUT -40* TO +150*C. AND UNDER A PRESSURE OF FROM ABOUT 0.1 TO 50 ATMOSPHERES. THESE PRODUCTS ARE USEFUL AS PLASTICIZERS AND SOLVENTS FOR HALOGENATED POLYMERS.
