    摘要: A sensor arrangement including a probe and a bracket that are provided for a calorimetric mass flow meter for measuring the mass flow in a measuring tube. The probe is mounted in the bracket in such a manner that the probe is guided essentially without contact with a radial spacing through a probe recess a wall of the measuring tube and is positioned in a cross section of a flow-through area of the flow of the measuring tube. The bracket is designed in such a manner that the probe is thermally de-coupled from the measuring tube. The sensor arrangement for the calorimetric mass flow meter is capable of increasing the measuring accuracy and increasing the flexibility during operation.

    摘要: The present invention relates to a process for the production of impact-modified filled polycarbonate compositions and molding compositions. A process of the present invention involves: (i) mixing the CNT (component C) with rubber-containing vinyl copolymer (component B) and/or rubber-free vinyl copolymer (component D) on a twin screw extruder, to obtain a CNT masterbatch, (ii) mixing the CNT masterbatch with polycarbonate (component A) and optionally with Component B and/or Component D and optionally with an additive on a twin screw extruder. A polycarbonate composition prepared according to the present invention does not experience degradation of the molecular weight of the polycarbonate during compounding a compared to processes known in the art.
