Abstract: A process is disclosed for preparing products from the reaction of polyasparaginic acid imides with aminoacids by reacting aminoacids with polyasparaginic acid imides in an aqueous medium at pH values at which at least 5% of the amino groups of the aminoacids having a non-protonated form are in equilibrium with those having a protonated form. Also disclosed is the use of the thus obtained reaction products and of products from the reaction of polyasparaginic acid imides with alkanolamines or aminated C1-C30-fatty alcohol alkoxilates which contain up to 50% by moles of polymerized ethylene and/or propylene oxide per mole of fatty alcohol. These products are useful as additives for washing and cleaning agents, as scale inhibitors and as dispersing agents.

Abstract: Process for the preparation of polymers of aspartic acid by reacting (a) maleic anhydride and (b) ammonia and/or primary or secondary amines without diluent in the (a) : (b) molar ratio of 1 : 0.1 to 1 : 3 to give monoamides of maleic acid, fumaric acid or their ammonium salts at up to 100.degree.C and subsequent condensation of the reaction products, with or without compounds capable of cocondensation, at above 100.degree.C and, where appropriate, hydrolysis of the condensates and use of the polymers as scale inhibitor, as dispersants for pigments and as additive to detergents and cleaners.

Abstract: Soluble polyacetals containing acetaldehyde acetal units are obtainable by cationically initiated addition polymerization of (a) compounds containing at least 3 hydroxyl groups, and (b) divinyl ethers containing terminal vinyl ether groups, or mixtures of such divinyl ethers and monovinyl ethers, in the presence or absence of (c) dihydroxy compounds and/or monohydroxy compounds, and are useful as admixture in phosphate-reduced and phosphatefree detergents and cleaners and as dispersant for finely divided minerals.

Abstract: Oxyalkylated, carboxyl-containing polymers are prepared by reacting (A) a polymer which contains one or more monoethylenically unsaturated C3-C6-carboxylic acids as copolymerized units with (B) an alkylene oxide in an aqueous medium at not more than 120 DEG C. by a process in which the reaction is started at a pH of from 5.0 to 5.9 and is ended after a pH of from 5.5 to 8.5 has been reached. As a result of monitoring of the pH, the selectivity of the addition reaction of alkylene oxides with the polymers (A) is substantially improved compared with known processes.

Abstract: A process for the preparation of water-soluble copolymers having K values of from 8 to 100 (determined on the sodium salt of the copolymers by the method of H. Fikentscher in aqueous solution at 25 DEG C, a pH of 7 and a polymer concentration of the sodium salt of 1% by weight) by copolymerising monomer mixtures of… a) from 98.5 to 18.5 mol % of at least one monoethylenically unsaturated C3- to C6-monocarboxylic acid,… b) from 1.5 to 20 mol % of at least one comonomer containing at least two ethylenically unsaturated, non-conjugated double bonds which are separated from one another by at least one ester bond,… c) from 0 to 80 mol % of at least one monoethylenically unsaturated C4- to C6-dicarboxylic acid or the anhydride thereof and… d) from 0 to 20 mol % of other monoethylenically unsaturated comonomers which are copolymerisable with the monomers (a), (b) and (c),… the data in mol % of (a) to (d) always totalling 100, in the presence of polymerisation initiators and polymerisation regulators at temperatures of up to 200 DEG C in at least one inert organic solvent.
