Abstract
An improved method of imparting salt and/or mechanical stability to an aqueous polymer microsuspension comprising admixing with the microsuspension a stabilizing amount of a mono- and dialkyldiphenyl ether sulfonate surfactant composition comprising, by weight, at least about 35 weight percent, based on the total weight of the composition, of at least one dialkyldiphenyl ether sulfonate.

In a method of imparting salt and/or mechanical stability to an aqueous polymer microsuspension by admixing with the microsuspension a stabilizing amount of a mono- and dialkyldiphenyl ether sulfonate surfactant composition, the improvement wherein at least about 35 weight percent of the composition is at least one dialkyldiphenyl ether sulfonate of the formula ##STR2## wherein:
- each R is an alkyl radical and each R can be the same or different,
- each M.sup..sym. is a hydrogen, alkali metal ion, alkaline earth metal ion or ammonium ion and each M.sup..sym. can be the same or different, and
- x and y are individually 0 or 1 with the proviso that x or y is 1 and the average value of .SIGMA.(x+y) for all (I) is at least about 1.7.
