Abstract: Flexible foams based on olefin polymers or thermoplastic polyesters comprise more than 40% open cells and have a density of less than 300 g/l and an average cell diameter of less than 0.1 mm. Independent claims are also included for: (1) a process for producing the foams, comprising extruding a polymer melt together with 2-40 wt.% of a strongly nucleating liquid propellant; and (2) use of flexible, open-celled, microcellular extruder foams based on thermoplastic polymers to produce liquid-absorbing hygiene articles. 24

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.
