Abstract: The invention relates to the essentially salt-free coagulation of plastic or rubber dispersions using shearing forces. A device with at least one shearing element (3) is used to this end. Said device has a stator (7) and a rotor (9) which is arranged inside said stator, the surfaces of the stator and the rotor that point towards each other each being flat. Alternatively, at least the rotor has a structure which is configured on its surface and which points in the direction of the stator from said surface. A gap (11) with a predetermined gap width is configured between the stator and the rotor. The method is carried out in such a way that the dispersion to be coagulated is guided through the gap (11) between the stator (7) and the rotor (9) and precipitated through the rotation of the rotor at a predetermined shear speed and with a predetermined shear deformation.

Abstract: A method for the production of additive dispersions containing water, additive(s) (A) with a melting point (TA) below 95 deg C and additive(s) (B) with a m.pt. of 95 deg C or above involves: (1) mixing water, emulsifier and (A) at between TA and 95 deg C to form an emulsion; (2) cooling to TA or below to form a dispersion; and (3) mixing with solid, finely-divided (B). An Independent claim is also included for additive dispersions obtained by this method.
