20080221231 | Porous Bodies and Method of Production Thereof - The invention provides a method for preparing water dispersible or water soluble porous bodies and the 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 lattice containing less than 10% by weight of a water soluble polymeric material and 5 to 90% by weight of a surfactant, with the proviso that said porous bodies are not spherical beads having an average bead diameter of 0.2 to 5 mm. The method comprises the steps of: a) providing an intimate mixture of the polymeric material and the surfactant in a liquid medium b) providing a fluid freezing medium at a temperature effective for rapidly freezing the liquid medium; c) cooling the liquid medium with the fluid freezing medium at a temperature below the freezing point of the liquid medium for a period effective to rapidly freeze the liquid medium; and d) freeze-drying the frozen liquid medium to form the porous bodies by removal of the liquid medium by sublimation. | 09-11-2008 |
20090082479 | FUSED AEROGEL-POLYMER COMPOSITE, METHODS OF MANUFACTURE THEREOF AND ARTICLES COMPRISING THE SAME - Disclosed herein is a method of preparing a fused aerogel-polymer composite in which aerogel and an organic polymer is mixed in a dry state to adsorb polymer particles on the surface of the aerogel and are then subjected to thermal treatment, thus forming a polymer coating on the aerogel. The fused aerogel-polymer composite can be used for thermal insulation in a variety of applications. The fused aerogel-polymer composite exhibits high thermal insulation properties and superior physical strength and processability while still maintaining the properties of an aerogel that does not have a polymer coated on its surface. | 03-26-2009 |

20120071577 | USE OF ISOCYANATES BASED ON RENEWABLE RAW MATERIALS - The invention relates to the use of 2,5-diisocyanato-1,4:3,6-dianhydro-2,5-dideoxy-D-manitol (I), 2,5-diisocyanato-1,4:3,6-dianhydro-2,5-dideoxy-D-glucitol (II), and/or 2,5-diisocyanato-1,4:3,6-dianhydro-2,5-dideoxy-L-iditol (III). | 03-22-2012 |
20120088857 | POLYMER REINFORCED POROUS MATERIAL AND METHOD OF MAKING SAME - A method of forming a porous material having improved compressive strength, includes forming an aerogel precursor that includes a polymer having a functional group capable of undergoing a crosslinking reaction dispersed in a dispersion medium. The precursor also includes a crosslinking agent. The aerogel precursor is frozen so that the dispersion is solidified, and freeze dried to sublime the dispersion medium and form the porous material. The crosslinking agent is reacted with the functional group to effect crosslinking, thus improving the compressive strength of the porous material. | 04-12-2012 |
20130018119 | FILTER MATERIAL FOR SEPARATION OF HYDROPHILIC SUBSTANCES FROM VARIOUS HYDROPHOBIC LIQUIDS OR GASES AND METHOD FOR PREPARATION OF THE MATERIALAANM Chipizubov; VitaliAACI PeterburiAACO RUAAGP Chipizubov; Vitali Peterburi RUAANM Post; PriitAACI HarjumaaAACO EEAAGP Post; Priit Harjumaa EEAANM Peterson; ReneAACI TallinnAACO EEAAGP Peterson; Rene Tallinn EEAANM Kaevand; ToomasAACI TallinnAACO EEAAGP Kaevand; Toomas Tallinn EE - A filter material and method for its preparation for separation of hydrophilic substances from environment of various hydrophobic liquids or gases. Such hydrophobic substances can be different chemical and oil products, substances of biological origin (fats, essential oils). Hydrophilic substance can be water, lower alcohols (methanol, ethanol), polybasic alcohols, substances dissociating in aqueous solution (salts, acids or bases). Filter material is in the form of oxygen containing polymer, which microscopic and macroscopic structure forms during polymerization process. More precisely the filter material consists of polyacetal for example polyvinylacetal. Polymeric structure of filter material forms during synthesizing reaction of the polyacetal by the action of the assisting substances taken into reaction medium. | 01-17-2013 |
