ABSTRACT:
Compounds of the invention are obtained by oxyalkylating natural rosin acids, disproportionated rosin acids or rosin acids modified with aromatic hydroxy compounds or with cycloalkyl and especially aralkyl and aryl compounds capable of splitting off halogen, and the esterification products thereof with polyols, and furthermore by oxalkylating rosin alcohols, rosin maleinates and/or mixtures of the above-mentioned rosin substances with ethylene oxide and/or propylene oxide; reacting the alkylene oxide addition products thus obtained with maleic acid anhydride; and then adding alkali metal sulfite or alkaline earth metal sulfites or hydrogen sulfites to the maleic acid semiesters. These compounds are useful as interface-active agents, especially as dispersing agents for the fine division and stabilization of solids, and as wetting, emulsifying, levelling and dyeing auxiliaries.
