Abstract

Alkoxylated, condensed basic amino acid-containing polymers comprising the addition products of alkylene oxides withhomocondensates of basic amino acids,condensates of mixtures of two or more basic amino acids andcocondensates of basic amino acids and cocondensable compounds,and a process for the production of alkoxylated, condensed basic amino acid-containing polymers which comprises reactinghomocondensates of basic amino acids,condensates of mixtures of two or more basic amino acids andcocondensates of basic amino acids and cocondensable compoundswith at least one alkylene oxide selected from the group consisting of C2- and C30-alkylene oxides and styrene oxide.
