- 26 - O.Z. 0050/42612 Abstract of the Disclosure: Water-in-oil emulsions of water-soluble or water-swellable polymers, in which the oil phase of the emulsion consists of not less than 50% by weight of an oil of vegetable or animal origin, contain, as water-in oil emulsifiers, compounds which are obtainable by (A) reacting a C10-C22-fatty alcohol with epichlorohydrin in a molar ratio of from 1 : 0.5 to 1 : 1.5 to give a glycidyl ether, (B) reacting the glycidyl ether with (1) a saturated C2-C6-alcohol containing from 2 to 6 OH groups or (2) the monoether thereof with a C10-C22-fatty alcohol, in a molar ratio of glycidyl ether to (1) or (2) of from 1 : 0.5 to 1 : 6, in the presence of an acid or base and (C) alkoxylating the reaction product from (B) with one or more C2-C4-alkylene oxides in a molar ratio of from 1 : 1 to 1 : 6, if necessary, from 5 to 95% by weight of the stated water-in-oil emulsifier being replaced with other water- in-oil emulsifiers.
