摘要： A method for preparing a polymer-organoclay composite composition comprises combining a solvent and an unexfoliated organoclay to provide a first mixture, wherein the unexfoliated organoclay comprises alternating inorganic silicate layers and organic layers, and has an initial spacing between the silicate layers; exposing the first mixture to an energized condition of a sufficient intensity and duration to increase the initial spacing of the inorganic silicate layers, to provide a second mixture; contacting the second mixture with a polymer composition so that the polymer composition fills at least one region located between at least one pair of silicate layers, wherein the polymer composition is at least partially soluble in the solvent; and removing at least a portion of the solvent from the second mixture, wherein the inorganic silicate layers remain separated by the polymer after removal of the solvent.

摘要： Methods for making hollow silica particle are disclosed, said particles made from a composition comprising a silicon-containing compound selected from the group consisting of tetraalkoxysilanes, trialkyloxysilanes and derivatives thereof, dialkoxysilanes and derivatives thereof, alkoxysilanes and derivatives thereof, silicone oligomers, oligomeric silsesquioxanes and silicone polymers distributed over a polymer template core that is eliminated from the particle. The particles of the present invention have a substantially uniform particle size and exhibit low permeability to liquids.
