PCT No. PCT/EP91/00310 Sec. 371 Date Oct. 28, 1992 Sec. 102(e) Date Oct. 28, 1992 PCT Filed Feb. 19, 1991 PCT Pub. No. WO91/13140 PCT Pub. Date Sep. 5, 1991.A pourable aqueous liquid surfactant concentrate containing from about 50 to about 90% by weight of a surfactant mixture comprising: A) from about 10 to about 90% by weight of at least one compound of the formula R1-O-(CH2-CH2O)n-H(I) in which R1 is a saturated or unsaturated hydrocarbon radical of a primary C8-22 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 (II) in which R2 is a saturated or unsaturated C6-14 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.
