Abstract (en)
[origin: DE4428597A1] Disclosed is a method for producing condensation polymers of aspartic acid by means of condensation polymerization of aspartic acid at temperatures of 140 DEG C in the presence of, relative to aspartic acid, from 1 to less than 5 mol % phosphorous acid or hypophosphorous acid catalyst, and the use of the resulting condensation polymers of aspartic acid as additives in washing and cleaning products, amounting to 0.1 to 10 wt % relative to the washing and cleaning products.
