    Abstract: Oxyalkylated addition products from ethylene oxide-propylene oxide block polymers and bis-glycidyl ethers, obtained by the addition of ethylene oxide-propylene oxide block polymers of the formula wherein R denotes methyl or ethyl, n and m are numbers which are so chosen that the content of polyethylene oxide groups is 5 to 80% of the molecular weight of the block polymer, and p is a number larger than 10, to bis-glycidyl ethers of the formula +TR wherein the R1's can be identical or different and denote hydrogen, C1-C4-alkyl or halogen, in particular chlorine, A denotes a direct bond, a sulfonyl or cyclohexyl group or a group of the formula R2 denotes hydrogen, methyl or phenyl, and a denotes an integer from 0 to 10, and subsequent oxyalkylation with propylene oxide or butylene oxide and, if appropriate, ethylene oxide, the amount of propylene oxide or butylene oxide which is added last being 1 to 90% by weight of the total molecule and the amount of ethylene oxide which, optionally, has also been added, being 50% by weight of the total molecule. These addition compounds are used for breaking crude oil emulsions.
