    • 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 C.sub.10 -C.sub.22 -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 C.sub.2 -C.sub.6 -alcohol containing from 2 to 6 OH groups or (2) the monoether thereof with a C.sub.10 -C.sub.22 -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 C.sub.2 -C.sub.4 -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.
    • 水溶性或水溶胀性聚合物的油包水乳液,其中乳液的油相由不少于50重量%的植物或动物来源的油包含作为油包水 乳化剂,可通过(A)使C 10 -C 22脂肪醇与摩尔比为1:0.5至1:1.5的表氯醇反应得到缩水甘油醚得到的化合物,(B)缩水甘油醚与(1) 含有2至6个OH基团的饱和C 2 -C 6醇或(2)其单醚与C 10 -C 22脂肪醇,缩水甘油醚与(1)或(2)的摩尔比为1:0.5 至1:6,在酸或碱的存在下,和(C)将(B)的反应产物与一种或多种摩尔比为1:1至1:6的C 2 -C 4 - 氧化烯烷氧基化,如 必要时,将所述油包水乳化剂的重量从5至95%重量替换为其它油包水乳化剂。
