| 摘要 |
The invention relates to surface-active compounds of the general formula (I) <IMAGE> (I) in which Ar is an aromatic system which is optionally substituted by C1-C18-alkyl, C1-C18-alkoxy, C2-C5-alkanoyl, C6-C10-aryl, (C6-C10-aryl)-C1-C4-alkyl, A has the formula -(X-O)n-Y, wherein n denotes 1 to 50, X denotes ethylene or methylethylene and all or some of Y denote an acyl radical of a non-modified or modified natural resin acid and the other radicals Y denote radicals from the group comprising hydrogen, acyl radicals of saturated C1-24-carboxylic acids, unsaturated C3-24-carboxylic acids, C2-24-hydroxy-fatty acids or C8-18-alkyl-, -alkenyl- and -alkylidene-succinic acids, maleic acid, fumaric acid, sulfosuccinic acid, sulfuric acid, benzodicarboxylic acids and C1-16-n-alkanedicarboxylic acids, W is a group -CHR- or -CHR-N(R*)-T-N(R*)-CHR-, wherein R*is hydrogen, C1-C4-alkyl, C2-C4-hydroxyalkyl, a radical A or -C2-C4-alkylene-O-A and R is H or C1-9-alkyl, T is C2-C12-alkylene, which is optionally interrupted by -O- or -NR'-, R' is H, C1-C4-alkyl, C2-C4-hydroxyalkyl, A or C2-C4-alkylene-O-A, W* is H or -CHR-N(R*)-T-N(R*)A and m is 1 to 16. The compounds are prepared on the basis of oxyalkylated novolaks of the formula (I) in which all the radicals Y denote hydrogen. The polyalkylene glycol chains are now terminally esterified or half-esterified in a one- or multi-stage reaction in accordance with the definition of A. The resulting surface-active products are suitable as emulsifiers and dispersing agents for the most diverse fields of applications.
