摘要:
The invention relates to polymers that can be obtained by: A) reacting an epoxidized ester, which is selected from one or more unsaturated fatty acids having 8 to 26 C atoms and a polyol having 2 to 6 OH groups, with a monoamine, diamine or polyamine; B) alkoxylating the polyamine obtained hereby with a C2 to C4 alkylene oxide in molar excess so that the average degree of alkoxylation per OH group ranges from 1 to 100. The polymers have a numerical average molecular weight ranging from 500 to 100,000 g/mol. The invention also relates to the use of these polymers in quantities ranging from 0.0001 to 5% by weight with regard to the oil as demulsifiers for oil-in-water emulsions.
摘要(中):
本发明涉及可以通过以下方法获得的聚合物:A)使选自具有8至26个C原子的一种或多种不饱和脂肪酸和具有2-6个OH基团的多元醇的环氧化酯与单胺,二胺或 多胺 B)以C摩尔过量的方式将C 2 N 2 C 2 C 2 O 3烷氧基化,使得每OH基团的平均烷氧基化度在1至100范围内。 聚合物的数均分子量为500〜100,000g / mol。 本发明还涉及这些聚合物在0.0001至5重量%范围内的用途,作为油包水乳液的破乳剂。
