摘要： Shear forces are used for essentially salt-free coagulation of plastics dispersions or rubber dispersions. For this, method of use is made of an apparatus with at least one shearing module which has a stator and a rotor arranged within the stator, where the surfaces facing toward one another in the stator and in the rotor are in each case smooth, or at least the rotor exhibits a structure formed on its surface and facing from this in the direction of the stator, and between the stator and the rotor there is a gap of predetermined gap width. The process is carried out by passing the dispersion to be coagulated through the gap between stator and rotor and precipitating the dispersion by rotation of the rotor with predetermined shear rate and shear deformation.

摘要： Aqueous non-self-emulsifying polymer dispersions having small particles and a long shelf life and based on highly viscous reaction resins are prepared without the addition of solvents, by means of an intensively dispersing screw apparatus, by a continuous process in which the preparation of the polymer dispersion is carried out in an intensive shear zone of the screw apparatus, the water/reaction resin ratio in this intensive shear zone corresponding to the phase inversion point or being close to it, and the specific energy supply is 0.01-0.15 kWh/kg, the residence time is 0.1-60 sec and the shear gradient is 2,000-20,000 sec.sup.-1.
