Abstract: New polymer concentrates on the basis of polymer additives, like e.g. fillers and flame-retardants, are provided which have in particular an increased bulk density compared to the polymer additives as such. This increased bulk density leads to a substantial improvement in the processability of such concentrates, their dispersibility during compounding and the properties of the resulting polymer compound. Processing improvements include less dust, faster processing and more homogeneous additive dispersion. The invention also provides a process for preparing such new polymer concentrates, a process for preparing polymer compounds containing the new polymer concentrates, the respective polymer compounds and a process for preparing formed parts thereof. Such formed parts have more uniform properties such as density, wall thickness, and in case of the flame-retardants more homogeneous and consistent flame retardancy.

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.

Abstract: A novel process is used to prepare synthetic rubbers (B) which feature very narrow molecular weight distribution and a correspondingly low value for the polydispersity index. The preparation process encompasses the treatment of a synthetic rubber with ultrasound, where the resultant synthetic rubber (B) has a lower weight-average molecular weight (Mw) than the synthetic rubber (A) used. The resultant synthetic rubbers (B) have excellent suitability for processing via extruder processes or injection-moulding processes.
