Nathalie Meeschaert has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Latex having a high solids content and a low viscosity and exhibiting a bimodal distribution
    Patent number: 6852812
    Abstract: A process is presented for the preparation of a latex by the emulsion polymerization at a temperature of between 30 and 90 C. of at least one ethylenically unsaturated monomer in the presence of at least one surfactant and of a seed of polymer particles with a diameter of between 200 and 450 nm. The seed particles represent from 5-25% by weight of the total weight of the monomer and seed. The polymerization is initiated by a mixed water-soluble/fat-soluble system. Also included are lattices obtained from this process.

  • Latex with high non-volatile matter content, low viscosity and having a bimodal distribution
    Publication number: 20030055150
    Abstract: The invention concerns a latex consisting of polymers dispersed in a bimodal distribution, having a non-volatile matter content at 55 % and low viscosity. Said latex is obtained by emulsion polymerisation of at least a monomer in the presence of a seed of polymer-based particles with a diameter ranging between 200 and 450 nm. The invention also concerns the use of said latex in various applications such as pressure sensitive adhesives, floor bonding adhesives, tile bonding adhesives, additives for mortar, sealants, sealing joints.
