  • Polymer composition with elastomeric properties at wide temperature ranges and process for the preparation thereof
    Patent number: 8039558
    Abstract: It is depicted a polymer composition with elastomeric properties at wide temperature ranges of the type comprising polymers and/copolymers resulting from substituted or unsubstituted vinyl aromatic monomers and from dienic monomers, which is homogeneous and compatible in nature, with such composition being based on stereoregular polymers and without requiring the additional use of compatibilizing agents. Likewise, it is depicted the process to obtain the same, as well as to hydrogenise them, without requiring the use of additional catalyzers or processes.
    Type: Grant
    Filed: July 28, 2010
    Date of Patent: October 18, 2011
    Assignees: Dyansol Elastomeros, S.A. de C.V., Centro de Investigacion en Quimica Aplicada (CIQA)
    Inventors: Sergei Kniajanski, Maricela Garcia-Zamora, Sergio Corona-Galvan, Rodolfo Flores-Flores, Marcela Garcia-Ramirez, Gregorio Cadena-Pliego
  • Polymer composition with elastomeric properties at wide temperature ranges and process for the preparation thereof
    Patent number: 7851552
    Abstract: The invention relates to a polymeric composition having elastomeric properties over wide temperature ranges, of the type that comprises polymers and/of copolymers which are derived from substituted or non-substituted vinylaromatic monomers and compatible, homogeneous diene monomers. The inventive composition is based on stereoregular polymers and does not require the use of compatibilizer agents. The invention further relates to the method of obtaining said compositions and of hydrogenating same without the need for additional catalysts or methods.
