Abstract (en)
[origin: FR2855827A1] A method for forming polymer films on mineral binder surfaces involves wet-on-wet coating with a polymer latex to which has been added a water-soluble amphiphilic copolymer, e.g. a copolymer or graft copolymer based on an unsaturated mono- or poly-carboxylic acid or anhydride and a non-aromatic unsaturated hydrocarbon, or a modified polymer of this type. A method for the deposition and formation of a film derived from an aqueous dispersion of film-forming polymer (A) on a surface based on a composition of still-wet mineral binders involves adding a sufficient amount of water-soluble amphiphilic copolymer(s) (B) to the dispersion. Copolymers (B) comprise (i) polymers obtained by the polymerisation of (i) unsaturated mono- or poly-carboxylic acids or their anhydrides (aliphatic, cyclic, linear or branched) (I) and non-aromatic mono-unsaturated hydrocarbons (linear or branched) (II), or (ii) graft copolymers of (II) with hydrophobic, non-aromatic optionally unsaturated 4-30C hydrocarbon chains, possibly with in-chain hetero-atom(s), or (iii) polymers obtained by chemical modification (e.g. esterification, transesterification or amidation) of precursor polymers containing (a) sites onto which non-aromatic hydrophobic residues may be grafted (e.g. carboxylic acid or ester sites) and (b) carboxylic acid un its or precursors thereof. An independent claim is also included for compositions of mineral binders the surface of which is at least partly coated with a film obtained by drying an aqueous dispersion containing (A) and (B).
