Abstract

A pourable aqueous liquid surfactant concentrate containing from about 50 to about 90% by weight of a surfactant mixture comprising: PA1 A) from about 10 to about 90% by weight of at least one compound of the formula EQU R.sup.1 --O--(CH.sub.2 --CH.sub.2 O).sub.n --H (I) PA1 in which R.sup.1 is a saturated or unsaturated hydrocarbon radical of a primary C.sub.8-22 alcohol attached by carbon and n is a number of from 10 to 60; and B) from about 90 to about 10% by weight of at least one compound of the formula ##STR1## in which R.sup.2 is a saturated or unsaturated C.sub.6-14 radical attached by carbon, and p and q are each a number of from 0 to 25, the sum of p and q being a number from of 5 to 25. The invention also relates to a process for the preparation of the above surfactant concentrate and to the use of the concentrate in emulsion polymerization reactions.
