The present invention relates to a water redispersible
powder composition based on a
copolymer of a)
vinyl acetate, b)
ethylene, c) optionally one or more auxiliary monomers, and d) optionally one or more additional ethylenically unsaturated monomers. The invention is characterized by comprising one or more amino compounds (
nitrogen compounds), the auxiliary
monomer c) is selected from the group consisting of polyoxyalkylene amines, polyethyleneimine, aliphatic polyamines and compounds of formula R-NR 'H wherein in formula R-NR' H, the group R is a linear or branched, optionally substituted hydrocarbyl group having 1 to 20 carbon atoms and R 'is a
hydrogen atom, an NH2 group or a
carbonyl group, with the proviso that the auxiliary
monomer c) is selected from ethylenically unsaturated monocarboxylic acids and dicarboxylic acids; an ethylenically unsaturated
carboxylic acid nitrile; an
acrylamide (CH2CHCONH2), an
acrylamide (CH2CHCONH2); an ethylenically unsaturated
sulfonic acid; an ethylenically unsaturated
silicon functional monomer; and hydroxyethyl
acrylate, hydroxypropyl
acrylate or hydroxybutyl
acrylate or hydroxyethyl methylacrylate, hydroxypropyl methylacrylate or hydroxybutyl methylacrylate, the further ethylenically
unsaturated monomer d) is selected from the group consisting of
methyl acrylate,
methyl methacrylate,
ethyl acrylate, ethyl
methacrylate, propyl acrylate, propyl
methacrylate, n-
butyl acrylate, n-
butyl methacrylate, 2-ethylhexyl acrylate, norbornyl acrylate, vinyl aromatic compounds and vinyl halides; and the water-redispersible dispersible
powder composition does not contain any compound with an
epoxy group (
epoxy compound).
