    摘要: The present invention relates to a dispersion of hybrid organic-inorganic nanocomposite molecules comprising discrete inorganic silica nanoparticles that are covalently bonded to organic polymers, wherein the dispersion has a high solid content (>30% wt.) and high silica content (>35% wt.) with low coagulum (about 100-400 ppm or about 0.05% wt or less). The hybrid organic-inorganic nanocomposite is prepared by (1) hydrolyzing silane monomers at acidic conditions; (2) surface treating inorganic silica nanoparticles with silane monomers; (3) stabilizing the surface-treated inorganic silica nanoparticles with an amine stabilizer; and (4) reacting organic monomers with surface-treated inorganic silica nanoparticles.

    摘要: The present invention relates to paint extenders or open-time extenders, which are mixed with an architectural coating, such as aqueous latex paints, to increase the coating's open time. The open-time extender comprises acrylic or vinyl latex particles having a mean diameter of less than about 150 nm, and at least one crosslinkable monomer that can crosslink the latex particles in the open-time extender to the latex particles in the architectural coating at ambient conditions. The open-time extender also comprises water and the total solid content of the open-time extender is less than about 15% by weight.

    摘要: The invention is directed to latex compositions comprising sequentially designed polymer having a first stage, a second stage and a third stage corresponding to a seed, a core and a shell. The latex polymer is suitable for aqueous low volatile organic compounds (“VOC”) paint (less than 50 g/L) with good block resistance, improved open time and increased water softening resistance. To attain good block resistance, the seed and the core contain monomers that form polymers with relatively harder characteristics and higher glass transition temperature (“Tg”) while the shell contains monomers that form polymers with softer characteristics and lower Tg. To gain improved open time, the latex polymer contains suitable level of hydrophilic monomers necessary to hold water. To achieve water softening resistance, hydrophobic monomers are grafted on hydrophilic portions of the shell or the core layers. The invention is also directed to the process of making the latex by a sequential emulsion polymerization.
