摘要:
Halogenated polycondensates of fatty alcohol-acids are prepared by the following steps:A. polycondensation of said fatty alcohol-acid in a solvent,B. halogenation of the polycondensate obtained in step (a)C. salification of the halogenated polycondensate obtained in step (b) by an alkaline and/or an amine and/or ammonium base.The polycondensates may also be esterifired with a mineral acid.The products are used in aqueous solutions for metal working.
