Abstract: A NEW CLASS OF POLYMER COMPRISING A MAIN CARBON CHAIN AND HAVING POLYFLUOROPOLYETHER SIDE GROUPS. THE POLYMERS POSSESS EXCELLENT SOIL AND WATER RESISTANT PROPERTIES AND ARE USEFUL FOR RENDERING FABRICS SOIL AND MOISTURE RESISTANT. THE POLYMERS ARE PREPARED FROM A NEW CLASS OF POLYMERIZABLE POLYFLUORINATED POLYMER ACRYLATES, METHACRYLATES, ACRYLAMIDES AND METHACRYLAMIDES. A NEW CLASS OF ALCOHOLS, USEFUL FOR PREPARING THE ACRYLATE AND METHACRYLATE MONOMERS IS DISCLOSED AND METHODS FOR PREPARING THE ALCOHOLS, MONOMERS AND POLYMERS ARE DISCLOSED.

Abstract: AT LEAST ONE OF THE LATTER TWO TERMINAL GROUPS BEING PRESENT WHEN-C6F6O- REPEATING UNITS ARE PRESENT, WITH THE FURTHER PROVISO THAT WHEN SAID -CF2CO-CF3 TERMINAL GROUP IS PRESENT, ONE SAID OTHER TWO TERMINAL GROUPS IS ALSO PRESENT, AND THE CORRESPONDING ACYL HALIDES, LOWER ALKYL ESTERS AND METAL SATLS.

-CF2-COOH, -C(-CF3)-COOH, -CF2-CO-CF3

TERMINAL GROUP BONDED TO SAID CHAIN THROUGH AN ETHER OXYGEN, SAID POLYETHER HAVING TERMINAL GROUPS BONDED TO SAID CHAIN THROUGH AN ETHER OXYGEN, SAID TERMINAL GROUPS BEING SELECTED FROM THE GROUP CONSISTING OF

-CF2-CO-CF3

1. BIFUNCTIONAL PERFLUORINATED POLYETHERS AND MIXTURES THEREOF, HAVING CHEMICALLY REACTIVE TERMINAL GROUPS AT BOTH ENDS OF THE CHAIN, SAID POLYETHER HAVING 1 FROM 1 TO 100 REPEAING UNITS SELECTED FROM THE GROUP CONSISTING OF -C3F6O-, -C2F4O-, AND -CF2O-, WHREIN C2F6 AND C2F4 ARE PERFLUOROALKYLENE UNITS DERIVED FROM THE OPENING OF THE DOUBLE BOND OF A HEXAFLUOROPROPYLENE AND OF A TETRAFLUOROETHYLENE MOLECULE, RESPECTIVELY, THE DIFFERENT OXYPERFLUOROALKYLENE UNITS HAVING A RANDOM DISTRIBUTION ALONG THE CHAIN, THERE BEING NO MORE THAN 50 OFF ANY ONE OF SAID SPECIES OF REPATING UNITS, SAID -CF2OREPEATING UNITS BEING PRESENT ONLY WHEN EITHER OR BOTH OF SAID -C2FF4O- AND C3F6O- REPEATING UNITS ARE PRESENT, SAID -C2F4O -UNITS BEING PRESENT ONLY WHEN SAID -CF2O- UNITS ARE ALSO PRESENT, SAID C3F6O- UNITS BEING PRESENT ONLY WHEN EITHER SAID -CF2O- UNITS ARE ALSO PRESENT OR WHEN SAID POLYETHER CONTAINS A
