  • Aqueous reinforced rubber dispersions and their use for making latex foams
    Patent number: 8158691
    Abstract: 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.
