|20100065238||SILICA-BASED SOLS AND THEIR PRODUCTION AND USE - A process for producing an aqueous silica-based sol is disclosed wherein a cationic ion exchange resin having part of its ion exchange capacity in hydrogen form is contacted with an aqueous alkali metal silicate to form a slurry having a pH from 5.0 to 11.5 and/or having particle aggregation or microgel formation corresponding to a S value up to 45%; adjusting the pH using a material comprising an aluminium compound; and separating the resin from the slurry.||03-18-2010|
|20090293201||PROCESS FOR TREATING ANIMAL SKINS - The present invention pertains to a process for decreasing and/or drying skins which comprises contacting the skins to be degreased and/or dried with one or more extractor solvents which are able to dissolve both fat and water. Preferably, the extractor solvent is selected from the group consisting of dimethyl ether (DME), methylal, dioxolane, diethyl ether, methyl ethyl ketone, ethanol, propanol, and isopropanol. Most preferably, the extractor solvent is DME.||12-03-2009|
|20090124723||PROCESS FOR THE MODIFICATION OF BIODEGRADABLE POLYMERS - Process for the modification of a polymer or copolymer having the following general structure for one or more of the repeating units: (1) wherein n is an integer, m is an integer in the range 0 to 6, and R is selected from hydrogen, substituted or unsubstituted C||05-14-2009|
|20080200600||Polymer-Containing Composition, its Preparation and Use - Process for the preparation of a polymer-containing composition comprising the steps of (a) preparing a mixture of an inorganic anionic clay and a cyclic monomer and (b) polymerising said monomer. It has been found that intercalation of the anionic clay with organic anions prior to its use in a polymerisation reaction is not required. Neither is the use of a polymerisation catalyst or initiator.||08-21-2008|
