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).
