Reaction products prepared by processes which comprise reacting: A) at least one compound having the general formula I: R.sup.1(X).sub.3 (I) wherein each X group independently represents a halogen atom or one X group represents a halogen atom and two X groups represent an epoxy oxygen atom, which is attached to two adjacent carbon atoms in the R.sup.1 group to form an epoxy group, and R.sup.1 is an alkanetriyl group having from 3 to 10 carbon atoms; and B) at least one compound having the general formula II R.sup.2X(AO).sub.nY (II) wherein R.sup.2 represents a polyfluorinated organic group having from 1 to 36 carbon atoms and at least two fluorine atoms; X represents --O--, --S--, or NR.sup.3-- where R.sup.3 is hydrogen or a C.sub.1 C.sub.18 alkyl group; each AO group is independently an ethyleneoxy, 1,2-propyleneoxy, or 1,2-butyleneoxy group, n is a number of from 0 to 200; and Y represents hydrogen, a mercapto group, an amino group or a C.sub.1 C.sub.6 alkylamino group in place of a terminal --OH group, with the proviso that when Y is a mercapto, amino, or a C.sub.1 C.sub.6 alkylamino group, n is at least 1; are described.
