    Abstract: POLYSULFATE COMPOUNDS OF THE FORMULA:

    (R(CH2)M)2(OSO2)PO

    WHEREIN R AND M HAVE THE AFORE-STATED MEANINGS, WITH SULFUR TRIOXIDE IN AT LEAST ABOUT THE STOICHIOMETRIC PROPORTIONS FOR THE REACTION. THE NOVEL POLYSULFATES MAY BE READILY HYDROLYZED TO THE CORRESPONDING ALCOHOLS USING A DILUTE MINERAL ACID. CORRESPONDING MONOSULFATES KNOWN TO THE PRIOR ART MAY NOT BE HYDROLYZED TO THE CORRESPONDING ALCOHOLS IN THIS MANNER BUT REQUIRE THE USE OF HIGHLY CORROSIVE CONCENTRATED MINERAL ACIDS OR THE USE OF ALKALINE CONDITIONS TO CARRY OUT THE HYDROLYSIS. THE NOVEL POLYSULFATES MAY ALSO BE DIRECTLY CONVERTED TO THE CORRESPONDING FLUOROALKYL OR FLUOROCYCLOALKYL ACRYLATE OR METHACRYLATE COMPOUNDS BY CONTACTING THE POLYSULFATES WITH ACRYLIC OR METHACRYLIC ACID AT TEMPERATURES FROM ABOUT 80 C. TO ABOUT THE BOILING POINT OF THE REACTION MIXTURE FOR A PERIOD OF ABOUT 1-24 HOURS. THE CORRESPONDING MONOSULFATES MAY NOT BE SIMILARLY DIRECTLY ESTERIFIED TO THE ACRYLATE OF METHACRYLATE COMPOUNDS.

    R(CH2)MI

    WHEREIN R IS (A) A HALOALKYL GROUP HAVING FROM 1 TO 20 CARBON ATOMS IN WHICH THE TERMINAL CARBON ATOM IS SUBSTITUTED WITH MEMBERS SELECTED FROM THE GROUP CONSISTING OF FLUORINE, CHLORINE, BROMINE AND HYDROGEN ATOMS AND EACH CARBON ATOM OTHER THAN THE TERMINAL CARBON ATOM, WHEN PRESENT, IS SUBSTITUTED WITH HALOGEN ATOMS SELECTED FROM THE GROUP CONSISTING OF FLUORINE AND CHLORINE, OR (B) A PERHALOCYCLOALKYL GROUP HAVING FROM 3 TO 6 CARBON ATOMS IN WHICH EACH HALOGEN ATOM IS A MEMBER SELECTED FROM THE GROUP CONSISTING OF FLUORINE AND CHLORINE, WITH THE PROVISO THAT AT LEAST ONE FLUORINE ATOM IS ATTACHED TO EACH CARBON ATOM IN THE HALOALKYL OR PERHALOCYCLOALKYL GROUP; M IS AN INTEGER OF FROM 1 TO 3 AND P IS AN INTEGER OF FROM 2 TO 6, ARE PREPARED BY REACTING A FLUOROALKYL OR FLUOROCYCLOALKYL IODIDE CORRESPONDING TO THE GENERAL FORMULA:
