Abstract: A process is disclosed for preparing aspartic acid polycondensates. Finely dispersed aspartic acid is heated up to a temperature of at least 150 DEG C and polycondensation is carried out in the presence of a cocondensable monomer that contains at least one functional group and of acid catalysts so that the catalysts and if required the co-condensable monomers contact the aspartic acid, heated up to a temperature of at least 150 DEG C, only in the reaction zone in which polycondensation takes place.

Abstract: A process is disclosed for preparing aspartic acid polycondensates with improved biological degradability by thermal polycondensation of finely powdered aspartic acid in solid phase, at temperatures from 180 to 250 DEG C, until maximum 70 % by weight of the theoretically possible amount of water produced during polycondensation are removed from the reaction mixture. Also disclosed is the use of the thus produced polycondensates as additives for washing and cleaning agents and as scale inhibitors.

Abstract: The invention concerns polyacetal-block-containing polymers obtained by polymerizing, in the presence of initiators, carboxylic acid esters containing aldehyde groups and by reacting the polymers with at least bifunctional cross-linking agents, in the presence of acids or Lewis acids and optionally hydrolysing the ester groups thus incorporated in the polymer. The invention also concerns a method of producing polymers containing polyacetal blocks by polymerizing carboxylic acid esters containing aldehyde groups in the presence of initiators and reacting the polyacetals containing terminal hydroxy groups thus obtained with at least bifunctional cross-linking agents, in the presence of acids or Lewis acids, plus the use of the polymers thus obtained as additives in phosphate-free and phosphate-reduced washing and cleaning agents, as scale inhibitors and as dispersants for pigments.
