ABSTRACT:
The invention relates to surface-active compounds of the general formula (I) ##STR1## in which Ar is an aromatic system which is optionally substituted by C.sub.1 -C.sub.18 -alkyl, C.sub.1 -C.sub.18 -alkoxy, C.sub.2 -C.sub.5 -alkanoyl, C.sub.6 -C.sub.10 -aryl, (C.sub.6 -C.sub.10 -aryl)-C.sub.1 -C.sub.4 -alkyl, A has the formula --(X--O).sub.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 C.sub.1-24 -carboxylic acids, unsaturated C.sub.3-24 -carboxylic acids, C.sub.2-24 -hydroxy-fatty acids or C.sub.8-18 -alkyl-, -alkenyl- and -alkylidene-succinic acids, maleic acid, fumaric acid, sulfosuccinic acid, sulfuric acid, benzodicarboxylic acids and C.sub.1-16 -n-alkanedicarboxylic acids, W is a group --CHR-- or --CHR--N(R*)--T--N(R*)--CHR--, wherein R*is hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.2 -C.sub.4 -hydroxyalkyl, a radical A or --C.sub.2 -C.sub.4 -alkylene-O--A and R is H or C.sub.1-9 -alkyl, T is C.sub.2 -C.sub.12 -alkylene, which is optionally interrupted by --O-- or --NR'--, R' is H, C.sub.1 -C.sub.4 -alkyl, C.sub.2 -C.sub.4 -hydroxyalkyl, A or C.sub.2 -C.sub.4 -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.
