NOVEL FLUORINE-CONTAINING POLYETHER PHOSPHONIC ACID ESTER COMPOUND AND PROCESS FOR PRODUCING THE SAME

摘要

A fluorine-containing polyether phosphonic acid ester compound represented by the following general formula:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ(R 2 O)(R 1 O)P(O)(CH 2 ) a CF(CF 3 )[OCF 2 CF(CF 3 )] b O(CF 2 ) c O[CF(CF 3 )CF 2 O] d CF(CF 3 )(CH 2 )P(O)(OR 3 )(OR 4 )
(where R 1 , R 2 , R 3 and R 4 are hydrogen atoms, alkyl groups, cycloalkyl groups, aryl groups, alkylaryl groups, aralkyl groups, or any of the foregoing groups substituted with halogen atoms, and subscripts a, b, c, d, and e are in conditions of 2‰¦a+e‰¦ 8, b+d ‰¦28, and 1‰¦c‰¦ 10, and subscripts b and d may be 0). The fluorine-containing polyether phosphonic acid ester compound is produced by reaction of a fluorine-containing polyether dialkyl halide represented by the following general formula :
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒX(CH 2 ) a CF(CF 3 )[OCF 2 CF(CF 3 )] b O(CF 2 ) c O[CF(CF 3 )CF 2 O] d CF(CF 3 )(CH 2 ) e X
(X : Cl, Br or I)
with a phosphite compound represented by the following general forumula :
(R 1 O)(R 2 O)P(OR) and/or (R 3 O)(R 4 O)P(OR)
(R : a hydrogen atom or a lower alkyl group).
