The present invention relates to an aqueous reinforced rubber dispersion comprising: a) 51 to 90 wt-% of base latex polymer particles; and b) 10 to 49 wt-% of reinforcing latex polymer particles comprising structural units of aromatic vinyl monomers and conjugated diene monomers, the reinforcing latex polymer particles having a single glass transition temperature (Tg) from -25~C to 28~C as measured by differential scanning calorimetry (DSC), whereby the weight percentages are based on the total weight of polymer particles in the rubber dispersion and the base latex polymer particles have a Tg as measured by DSC that is lower than the Tg of the reinforcing latex particles, to the use of the rubber dispersion for making latex foam, to a method for making latex foam and to an article comprising the latex foam obtained from the rubber dispersion of the present invention.

La présente invention porte sur une dispersion aqueuse en caoutchouc renforcé contenant; a) entre 51 et 90 % en poids de particules de polymère en latex de base; et b) entre 10 et 49 % en poids de particules de polymère en latex renforcées comprenant des unités structurales de monomères vinyliques aromatiques et de monomères de diènes conjugués, les particules de polymère en latex renforcées présentant une température simple de transition vitreuse (Tg) comprises entre -25 °C et 28 °C selon les mesures effectuées par l'analyse calorimétrique à compensation de puissance (DSC), les pourcentages en poids étant fondées sur le poids total des particules polymères dans la dispersions en caoutchouc et, d'autre part, les particules de polymères en latex de base présentent une a Tg selon les mesures obtenues par DSC inférieure à la Tg des particules en latex renforcées. L'invention porte également sur l'utilisation de la dispersion en caoutchouc permettant l'obtention d'une mousse en latex, sur un procédé d'obtention d'une mousse en latex et sur un article comprenant la mousse en latex ainsi obtenue.
