  • Patent number: 4729904
    Abstract: Inert cross-linked copolymer able to absorb and then progressively release a pharmaceutically active substance, wherein it is constituted by a powder of a cross-linked copolymer comprising30 to 80% by weight of monounsaturated alkyl acrylate and/or methacrylate;5 to 68% by weight of acrylic and/or methacrylic acid; and2 to 15% by weight of bifunctional or trifunctional acrylate and/or methacrylate.A mixture of monounsaturated alkyl acrylate and/or methacrylate, acrylic and/or methacrylic acid, and bifunctional or trifunctional acrylate and/or methacrylate monomers is polymerized in accordance with a free radical polymerization mechanism.The support is used for the preparation of a delayed action or release medicament.
    Type: Grant
    Filed: August 7, 1985
    Date of Patent: March 8, 1988
    Assignee: Compagnie ORIS Industrie S.A.
    Inventors: Jeanne Berthet, Marie-Francoise Blin, Gilbert Gaussens

  • Patent number: 4557749
    Abstract: Device for conditioning hydrosoluble fertilizers and/or hydrosoluble products usable in agriculture, wherein it comprises a sealed container, whereof at least one of the walls is constituted by a hydrophobic polymer diaphragm having hydrophilic inclusions, said container containing the fertilizers and/or products.A process for preparing a hydrophobic polymer diaphragm containing hydrophilic inclusions and usable in the conditioning device consists of preparing a hydrophobic polymer powder grafted by hydrophilic monomers and bringing this powder into the form of a diaphragm by different processes performed hot.
