摘要： Resins obtainable from compounds of formula 1 in which the substituents R2 and HNR1 can be in the ortho, meta or para position relative to one another, and R1 has the same meaning as R2, or has the meaning —COR2, where R1 is independent of R2, R2 is C1-C30-alkyl, C2-C30-alkenyl, C6-C18-aryl, C7-C30-alkylaryl, by the steps, which can be carried out in any order, of A) reaction with an aldehyde of the formula 2 R3—CHO  (2), wherein R3 is H, C1-C30-alkyl, C2-C30-alkenyl, C6-C18-aryl or C7-C30-alkylaryl, and B) alkoxylation with a C2-C4-alkylene oxide in molar excess, such that the resulting alkoxylate has a degree of alkoxylation of from 1 to 100 alkylene oxide units per —NH group, and the resin has a molecular weight of from 250 to 100,000 units, and their use as emulsion breakers.
