    摘要: The invention discloses a new phosphomagnesium cement that can be obtained by contacting at least one phosphorus compound and at least one magnesium compound based binder phase, with at least one polymer in water insoluble particle form, and water. The polymer can be selected among those derived from the polymerisation of at least one ethylenically unsaturated monomer and at least one monomer selected among monomers with carboxylic function and acrylamide or methacrylamide. The phosphomagnesium cement can also comprise an aminoalkylsilane, preferably an aminoalkyl(alkoxysilane).

    摘要: A water-redispersible powder composition comprising (a) 100 parts by weight of a powder consisting of a water-insoluble film-forming polymer prepared from at least one ethylenically unsaturated monomer and at least one monomer selected from monomers having a carboxylic function and acrylamide or methacrylamide, and (b) 2-40 parts by weight and preferably 8-22 parts by weight of at least one amino acid or a salt thereof. A method for preparing said composition and the use thereof are also disclosed.
