| abstract |
POROUS BODIES, METHODS FOR PREPARING POROUS BODIES AND SOLUTIONS OR DISPERSIONS. The invention provides a method for preparing water-soluble or water-dispersible porous bodies and the porous bodies themselves. The bodies have an intrusion volume, as measured by mercury porosimetry, of at least about 3 ml / g and comprise a three-dimensional open cell reticulum containing less than 10% by weight of a water-soluble polymeric material and 5 to 90% by weight of a surfactant, provided that said porous bodies are not spherical globules having an average globule diameter of 0.2 to 5 mm. The method comprises the steps of: a) providing an intimate mixture of polymeric material and surfactant in a liquid medium, b) providing a fluid freezing medium at an effective temperature for rapidly freezing the liquid medium; c) cooling the liquid medium with the fluid freezing medium to a temperature below the freezing point of the liquid medium for an effective period to rapidly freeze the liquid medium; and d) freezing the frozen liquid medium to freeze the porous bodies by reacting the liquid medium by sublimation. |
