Abstract
Briefly, in one aspect, the present invention provides compositions of open-chain, .alpha.-branched fluoroalkylcarbonyl fluorides, and derivatives thereof.
Claims6
A composition comprising one or more .alpha.-branched fluoroalkylcarbonyl compounds of the formula:
- ##STR58## wherein:
- n is between 4 and about 18;
- n is between 0 and about 9;
- and
- X is a group of the formula --N(R.sup.1)(R.sup.2), --OR".sub.f, --YQOR, --YQN(R.sup.1)(R.sup.2), --YQZ, or --O.sup.- 1/qM.sup.q+ where R".sub.f is a fluorinated alkyl group and R, R.sup.1, and R.sup.2 are, independently from one another, selected as hydrogen, or an alkyl, aryl, alkaryl, aralkyl (or any combination thereof) group that may be substituted or unsubstituted, linear or branched, cyclic or acyclic, and may contain one or more catenary heteroatoms;
- where present, R.sup.1 and R.sup.2 together can form a heterocyclic ring;
- Y is O, S, or NR, where R is as defined supra;
- Q is a substituted or unsubstituted divalent organic group;
- M is a cation selected from the group consisting of H.sup.+, metal cation, ammonium cation, substituted ammonium cation, and polyammonium cation;
- q is equal to the valency of M;
- and Z is an anionic, cationic, nonionic or amphoteric water-solubilizing group or is an ethylenically unsaturated group.
