Abstract: Diclosed is a method for producing condensation polymers of aspartic acid by means of condensation polymerization of aspartic acid at temperatures of 140 to 300 DEG C in the presence of a sulfuric acid catalyst partially neutralized with ammonia and/or amines and the use of the reaction mixtures thus produced or of the reaction mixtures neutralized with alkali metal bases or alkaline earth metal bases as additives in phosphate-free or low-phosphate detergents and cleaners.

Abstract: A process is disclosed for preparing polyaspartic acid imides. A mixture of aspartic acid and phosphoric acid in a molar ratio from 1:0.8 to 1:3 is condensed at a temperature from 80 to 150 DEG C into a pre-condensate liquid in the reaction conditions, and the pre-condensate is then polycondensed under shearing at temperatures from 180 to 250 DEG C in a layer with 0.1 to 10 mm thickness.

Abstract: Amphiphilic polyesters having (a) ester units of polyalkylene glycols with a molar mass of 500 to 7,500 and aliphatic bicarboxylic acids and/or monohydroxy monocarboxylic acids and (b) ester units obtained from aromatic bicarboxylic acids and polyvalent alcohols and with molar masses of 1,500 to 25,000; process for producing the amphiphilic polyesters by polycondensation, in which first of all (a) aliphatic polyesters of polyalkylene glycols with a molar mass of 500 to 7,500 are produced with aliphatic bicarboxylic acids and/or monohydroxy monocarboxylic acids and then, in the aliphatic polyesters thus obtained, (b) aromatic polyesters are produced from aromatic bicarboxylic acids and polyvalent alcohols; the polycondensation sequence is reversed or oligomeric aromatic polyesters (b) are condensed with oligomeric aliphatic polyesters (a); and the use of the amphiphilic polyesters as additives in washing agents, other washing agent additives and washing after treatment agents.
