Claims: What is claimed is:

1. A thioethersulfonate independently selected from ##EQU1## wherein the following definitions delineate the scope of the above general formula:

M = na, K, NH.sub.4 or H;

R = an alkylene group containing 2 to 4 carbon atoms;

R.sub.1 = h, or alkyl group containing 1 to 4 carbon atoms;

R.sub.2 = h, or (CH.sub.2).sub.m X;

m = 1 - 2

X = -cn, or ##EQU2## R.sub.3, R.sub.4 = H, or alkyl group containing 1 - 4 carbon atoms; n = 0 to 3 with the proviso that when two X groups are present in the compound they are identical.

2. The thioethersulfonate of claim 1, wherein R is three carbon atoms.

3. The thioethersulfonate of claim 1, wherein R.sub.3 and R.sub.4 are hydrogen.

4. The thioethersulfonate of claim 1, of the structure: ##STR4##

5. The thioethersulfonate of claim 1, of the structure:

NC -- CH.sub.2 -- CH.sub.2 -- S -- (CH.sub.2).sub.3 -- SO.sub.3 Na

6. The thioethersulfonate of claim 1, of the structure: ##STR5##

7. The thioethersulfonate of claim 1, of the structure: ##STR6##
