  • Durable latex polymer dispersion
    Patent number: 11708465
    Abstract: A method for forming a durable latex polymer emulsion includes a step of forming a pre-emulsion by combining a monomer composition with a reactive emulsifier, a reactive silane compound, an epoxy crosslinker, and a phosphate-containing monomer in water. The pre-emulsion is polymerized by combining the pre-emulsion with a radical initiator to form a reaction mixture that polymerizes to form a hydride silicon-acrylic emulsion polymer.

  • POLYMERIC EMULSION CONTAINING AMPHOTERIC SURFACTANT AND ITS APPLICATION IN ARCHITECTURAL PRIMERS
    Publication number: 20220064340
    Abstract: A method for forming an acrylic emulsion includes a step of forming pre-emulsion by combining a monomer composition with an amphoteric surfactant in water and then polymerizing the pre-emulsion by combining the pre-emulsion with a radical initiator in a reactor to form a reaction mixture. The monomer composition includes one or more monomers selected from the group consisting of (meth)acrylic acid monomers and (meth)acrylic monomers, and combinations thereof. An acrylic emulsion formed by the method is also provided.
