    Abstract: The present invention relates to a mixing apparatus at least composed of a screw-based machine S 1 and a screw-based machine S 2 , where S 1 has heating equipment, at least in the plasticizing and homogenizing zone, and where the outlet from S 2 has been connected to the screw-containing barrel of S 1 , within the plasticizing or homogenizing zone of S 1 , a substantive feature of which is that the connection between S 1 and S 2 is brought about by a connector which has cooling equipment effective as far as the inner wall of the screw-containing barrel of S 1 , and to a process for preparing thermoplastically processable molding compositions, in particular additive masterbatches, from at least one thermoplastic component C 1 and at least one component C 2 , where the melting point or decomposition temperature T M C2 of C 2 is lower, by at least about 50° C., than the temperature T H C1 , which is the lower limit of the thermoforming range of C 1 , and where most of C 2 is melted only after contact with C 1.

    Abstract: The invention relates to a method for producing odorant polymers or plastics, wherein a crushed or fine particle first polymer material is mixed with the desired odorant, is allowed to swell during a predetermined period and then subjected to further treatment at a predetermined pressure and temperature. After swelling with the odorant, the first polymer material can be mixed with a second plastic material, wherein the first polymer material and the second plastic material can be identical or different from each. Odorant polymers can also be obtained by using a polymer as second plastic material. The invention also relates to the odorant polymer or the odorant plastic produced according to the inventive method and to a molding material or an object containing the odorant polymer or the odorant plastic.
