Title: Anionic and other derivatives of non-ionic surfactants, methods for making, and uses in emulsion polymerization and polymer dispersions

Abstract: An anionic surfactant concentrate and method for making includes providing compound (I) R.sup.1--OH where R.sup.1 represents a branched C.sub.6-22 radical with average branching of about 2-8 per radical; providing compound (II): ##STR00001## where R.sup.2 represents a C.sub.8-16 radical; mixing (I) and (II); ethoxylating to obtain a reaction product; reacting with a sulfating, phosphating, or sulfitation agent to obtain R.sup.1--O--[CH.sub.2--CH.sub.2O].sub.n-A and ##STR00002## where R.sup.1 represents a branched C.sub.6-22 radical with average branching of about 2-8, R.sup.2 represents a C.sub.8-16 radical, A represents --SO.sub.3M, --PO.sub.3M, --PO.sub.3M.sub.2, --OCCH.sub.2CH(SO.sub.3Na)COO--, or HOOCCH.sub.2CH(SO.sub.3Na)COO--, M represents a positive counterion, n represents a value from 0-100, and x and y each represents a value from 0-100, where the sum of x and y represents a value of at least 1 to 100 are provided. Anionic surfactant compositions containing the concentrate and methods for stabilizing are also provided.
