Abstract
Water-redispersible polymer powder compositions with accelerated-setting action based on homo- or copolymers of one or more monomers of vinyl esters of optionally branched Calkylcarboxylic acids, (meth)acrylic esters of Calcohols, vinylaromatics, olefins, dienes, and vinyl halides, one or more protective colloids, and optionally antiblocking agent(s), contain one or more setting-accelerants NR, RN—(CH)—NR, or one or more singly or doubly NH-terminated polyalkylene glycols having a C-C-alkylene group is/are present, where n=from 1 to 4, and where the radicals R are identical or different, and are hydrogen, a C-C-alkyl radical, or a C-C-hydroxyalkyl radical, where at least one radical R is a C-C-hydroxyalkyl radical, and wherein the setting-accelerants may optionally be present in the form of their salts.
