Patent attributes
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 C1-15 alkylcarboxylic acids, (meth)acrylic esters of C1-15 alcohols, vinylaromatics, olefins, dienes, and vinyl halides, one or more protective colloids, and optionally antiblocking agent(s), contain one or more setting-accelerants NR3, R2N—(CH2)n—NR2, or one or more singly or doubly NH2-terminated polyalkylene glycols having a C1-C6-alkylene group is/are present, where n=from 1 to 4, and where the radicals R are identical or different, and are hydrogen, a C1-C6-alkyl radical, or a C1-C6-hydroxyalkyl radical, where at least one radical R is a C1-C6-hydroxyalkyl radical, and wherein the setting-accelerants may optionally be present in the form of their salts.
