Patents Assigned to Dynasol Elastomeros, S.A.
  • Patent number: 9238765
    Abstract: The present invention relates primarily to polymers comprising at least one alkenyl aromatic monomer, at least one conjugated diene monomer, and at least one monomer containing silyl hydride moieties, characterized in that said polymers are hydrogenated and preferably functionalized by hydrosilylation reactions between the silyl hydride groups on the polymer chain and the multiple bonds of any alkene or alkyne compound. Besides the described products, this invention comprises their synthesis processes and their uses, especially as thermofusible adhesives, in plastics impact modification, and in chain-extension reactions to obtain new materials, among others.

  • Patent number: 9211532
    Abstract: Homogeneous catalyst based on titanium compounds of the type (R1Cp)(R2Cp)Ti(PhOR3)2, where Cp is a cyclopentadienyl group, R1 and R2 are identical or different alkyl radicals (C3-C10), Ph is a phenyl group and OR3 is an alkoxyl group. Moreover, the invention relates to the use of said catalyst in a method for the hydrogenation of double bonds in unsaturated compounds, preferably polymers and/or copolymers of conjugated dienes, under mild reaction conditions.

  • Patent number: 6875615
    Abstract: The present invention relates to sensors for the determination of organometallic compounds comprising the following elements: a) an inorganic, organic or polymeric support, insoluble in the sample to analyze b) an indicator which reversibly reacts with the organometallic compound and whose reaction product gives a characteristic absorption, reflection or emission band in the range 150-15000 nm and which is physically trapped, adsorbed, absorbed, dissolved or chemically linked in an electrostatic or covalent way to the support c) an optical sensor which measures the absorption, reflection or emission of the functionalized support at the characteristic wavelength and transforms it in the concentration of the organometallic present in the solution. Also described is the method for the determination of the concentration of organometallic compounds by the on line use of a sensor as above defined.
