Fluorinated diesters useful for imparting repellency of low surface tension fluids to thermoplastic polymers of formulae: Rf-O-C(O)-(CH2)n-C(O)-O-R1; Rf-O- C(O)-CH2-CH(R2)-C(O)-O-Rf; a mixture of Rf-O-C(O)-(CH2)n-C(O)-O-R1, Rf-O-C(O)- (CH2)n-C(O)-Rf, and R1-O-C(O)-(CH2)n-C(O)-O-R1; and [F(CF2)xCH2CH2-S-CH2]2-C- [CH2-O-C(O)-C17H35]2; wherein Rf is F(CF2)x-(CH2)m wherein x is 4 to 20 and m is 2 to 6, or F(CF2)x-SO2N(R3)-R4 wherein x is 4 to 20; R1 is a saturated aliphatic hydrocarbon with an average carbon chain length of 12 to 66 carbons; R2 is a saturated or unsaturated hydrocarbon with 1-20 carbon atoms; R3 is an alkyl radical having 1 to 4 carbon atoms; R4 is an alkylene radical having 1 to 12 carbon atoms; n is 1 to 20, and x is 4 to 20 are disclosed.
La présente invention concerne des diesters fluorés conférant le caractère répulsif spécifique des fluides de faible tension superficielle à des polymères thermoplastiques. Ces diesters sont représentés par les formules générales R¿f?-O-C(O)-(CH¿2?)¿n?-C(O)-O-R¿1?, R¿f?-O-C(O)-CH¿2? CH(R¿2?)-C(O)-O-R¿f?, un mélange de R¿f?-O-C(O)-(CH¿2?)¿n?-C(O)-O-R¿1?, R¿f?-O-C(O)-(CH¿2?)¿n?-C(O)-R¿f? et R¿1?-O-C(O)-(CH¿2?)¿n?-C(O)-O-R¿1?, et [F(CF¿2?)¿x?CH¿2?CH¿2?-S-CH¿2?]¿2?-C-[CH¿2?-O-C(O)-C¿17?H¿35?]¿2? où R¿f? est F(CF¿2?)¿x?-(CH¿2?)¿m?, x valant de 4 à 20 et m de 2 à 6, ou F(CF¿2?)¿x?-SO¿2?N(R¿3?)-R¿4?, x valant de 4 à 20. R¿1? est un hydrocarbure aliphatique saturé dont la longueur moyenne de chaîne de carbone va de 12 à 66 atomes de carbone. R¿2? est un hydrocarbure saturé ou insaturé portant 1 à 20 atomes de carbone. R¿3? est un radical alkyle portant de 1 à 4 atomes de carbone. R¿4? est un radical alkylène portant de 1 à 12 atomes de carbone. n vaut de 1 à 20, et x vaut de 4 à 20.
