摘要： Stabilized, water-soluble polymer powders based on polyoxyalkylene glycol carboxylates are described, wherein the powders comprise from 0.01 to 10% by weight of a stabilizer selected from the group consisting of phenols, amines, phosphites, thioethers, and also thioacids, and where the stabilizer was added in liquid or dissolved form to the aqueous polymer solution prior to its conversion into the powder form. The polymer powders thus protected against autoignition and oxidative degradation have unexpectedly high thermooxidative stability, even on exposure to high temperatures and oxidizing action (air, oxygen).

摘要： Water-soluble formaldehyde-free polycondensation products based on amino-s-triazines with at least two amino groups and glyoxylic acid, which contain as further component at least one amino compound and where the molar ratio of amino-s-triazine to glyoxylic acid to amino compound is 1:0.5 to 6.0:0.1 to 2.0. These polycondensation products are excellently suited as additives for aqueous suspensions of inorganic binders, especially cement, lime and gypsum. Building material mixtures which contain these polycondensation products remain workable for a considerably longer time and, in spite of this, also set more quickly.
