摘要： The present invention relates to resins obtained by reacting a compound of formula 1 with an aldehyde and alkoxylating, in any order: wherein X is —OH, Y is ortho-, meta- or para- to X and is a radical of formula 4, wherein R5 is a C1-C30-alkyl, C2-C30-alkenyl, C6-C18-aryl, or C7-C30-alkylaryl. The resin has a molecular mass from 250 to 100,000 and is useful in methods of breaking oil-water emulsions.
