Abstract

The present invention relates to perfluoroalkyl substituted sulfates and salts thereof of the formulas EQU (R.sub.f X CH.sub.2).sub.x C(CH.sub.2 OH).sub.y (CH.sub.2 OSO.sub.3 -M+).sub.z (I) EQU or EQU (R.sub.f E X CH.sub.2).sub.x C(CH.sub.2 OH).sub.y (CH.sub.2 OSO.sub.3 -M+).sub.z (II) wherein R.sub.f is a straight or branched chain perfluoroalkyl of 1 to 18 carbon atoms or said perfluoroalkyl substituted by perfluoroalkoxy of 2 to 6 carbon atoms, PA1 E is branched or straight chain alkylene of 1 to 10 carbon atoms or said alkylene interrupted by one to three groups selected from the group consisting of --NR--, --O--, --S--, --SO.sub.2 --, --COO--, --OOC--, --CONR--, --NRCO--, --SO.sub.2 NR-- and NRSO.sub.2 -- or terminated at the R.sub.f end with --CONR-- or --SO.sub.2 NR--, where R.sub.f is attached to the carbon or sulfur atom, and for formula II, X is --S--, --O--, --SO.sub.2 --, or --NR--, and for formula I, X is --CONR-- or --SO.sub.2 NR--, where R.sub.f is attached to the carbon or sulfur atom, and where R is independently hydrogen, alkyl of 1 to 6 carbon atoms or hydroxyalkyl of 2 to 6 carbon atoms; x is 1, 2 or 3; y is 0, 1 or 2; z is 1,2 or 3; x+y+z=4; M is independently …
