    Abstract: A polymer composed offrom 5 to 95% by weight of a mixture of at least one C2-C4-alkyl acrylate and at least one C6-C12-alkyl acrylate (monomers a),from 5 to 30% by weight of ethylenically unsaturated compounds having a glass transition temperature of above 0° C. and containing no functional groups other than the ethylenically unsaturated group (monomers b),from 0 to 10% by weight of ethylenically unsaturated compounds having at least one acid group or acid anhydride group (monomers c), andfrom 0 to 60% by weight of further ethylenically unsaturated compounds (monomers d),the amounts by weight being based on the emulsion polymer.

    Abstract: In the production of aqueous polymer dispersions by free radical emulsion polymerisation of monomers, a mini-emulsion (I) is added before or during polymerisation. (I) is an aqueous emulsion, stabilised with a surfactant, which contains emulsified monomer droplets with a particle size of 10-500 nm and a co-stabiliser, dissolved in the monomer, which is at least twice as soluble in the monomer as it is in water. Also claimed are polymer dispersions obtained in this way.

    IPC: C08F2/24

    Abstract: This is a process in order to prepare a dilute polymer dispersion by the emulsion polymerisation of the compositions that able to polymerise as free radically (monomers); contains addition of a mini emulsion prepared from dilute, surfactant containing a compound (common regulator) dissolved into drop monomers having emulsified drops between 10 and 500nm before or during the polymerisation of the monomers and its solubility inside the monomers is at least twice the solubility inside the water.

    Abstract: Procedimiento para la mejora de la estabilidad de dispersiones polímeras acuosas, que se obtienen por polimerización en emulsión acuosa por medio de radicales de monómeros M etilénicamente insaturados, que comprenden al menos un 50 % en peso, referido a la totalidad del peso de los monómeros M, de uno o varios monómeros M1, que se escogen entre monómeros vinilaromáticos, los ésteres alquílicos con 1 a 12 átomos de carbono y los ésteres cicloalquílicos con 5 a 8 átomos de carbono de ácidos mono- y dicarboxílicos etilénicamente insaturados con 3 a 8 átomos de carbono, butadieno, cloruro de vinilo y de vinilideno y olefinas con 2 a 6 átomos de carbono, frente a la influencia térmica y/o mecánica, caracterizado porque se agrega al menos una sal de un éster bisalquílico con 4 a 18 átomos de carbono de un ácido dicarboxílico sulfonado con 4 a 8 átomos de carbono (= sal S) a la dispersión polímera acuosa.
