Polyvinylalcohol stabilised redispersing powder with fluidising properties

A method of plastically of the polyvinyl alcohol stabilizing a redispersible powder, which is shortened is a copolymer of the following materials is formed: a) one or more selected from the 4-8 carbon atoms ethylenically unsaturated monocarboxylic acid, an ethylenically unsaturated carboxylic acid and their anhydrides and salt; b) one or more of a sulfonic acid, sulphuric acid and phosphine acyl and salt is polymerizable compound; c) one or more to the second branch or a linear alkyl carboxylic acid vinyl ester or 1-15 carbon atoms branched or the linear butyl acrylate and methacrylate; Dried silicon polyvinyl alcohol, stabilizing the one or more of monomer or copolymer aqueous dispersion, wherein said monomer is selected from an orthorhombic carbon atoms in a and a linear alkyl carboxylic acid vinyl ester, a 1-15 carbon atoms in a and wherein the ethyl acrylate and methacrylate, diene, alkenoates, vinyl aromatic compound of an ethylene.
