  • Process for preparing hydrogenated nitrile rubbers
    Publication number: 20070287806
    Abstract: The present invention provides a novel process for preparing hydrogenated nitrile rubbers comprising subjecting nitrile rubbers in a spinning disk reactor to hydrogenation. The present process is less demanding with regard to its reaction conditions, like e.g. the hydrogen pressure to be applied, compared to known processes and significantly reduces the cost of the hydrogenation process and in particular the equipment cost.

  • Low mooney nitrile rubber thermoplastic elastomer composition with improved processability
    Publication number: 20070208136
    Abstract: The present invention relates to thermoplastic vulcanizates (TPVs) based on low Mooney, optionally hydrogenated nitrile butadiene rubber and polyamides. The present invention also relates to TPVs based on low Mooney, optionally, hydrogenated nitrile terpolymers and polyamides. TPVs prepared according to the present invention have improved morphology, smaller rubber particle size, and improved processability compared to TPVs containing non-low Mooney, optionally hydrogenated nitrile butadiene rubber.

  • Process for the preparation of low mooney nitrile terpolymers
    Publication number: 20070049699
    Abstract: The present invention relates to a process for the production of optionally hydrogenated nitrile terpolymers having lower molecular weights, lower Mooney viscosities and narrower molecular weight distributions than those known in the art. The present invention also relates to optionally hydrogenated nitrile terpolymers having lower molecular weights, lower Mooney viscosities and narrower molecular weight distributions than those known in the art.
