| 20120021212 | Composite Polymeric Articles Formed from Extruded Sheets Containing a Liquid Crystal Polymer - A process for forming shaped three-dimensional products is described made from a composition containing at least one filler and an aromatic liquid crystal polymer. In one embodiment, the process includes forming a substrate such as a film, a sheet or a tube, through an extrusion process. Once the substrate is formed, the substrate is then heated and fed to a shaping process. The shaping process may comprise a thermal forming process or a blow molding process. In order to form the three-dimensional products, the aromatic liquid crystal polymer has a high heat of crystallization, a high melt temperature and/or a high melt viscosity. | 01-26-2012 |
| 20120006699 | Modularly Built Container for Cooked Food Preparations - The invention relates to a modular container for the preparation of foods, in particular baked goods, by cooking, comprising a self-supporting base plate ( | 01-12-2012 |
| 20110077378 | Oxymethylene Polymers and Process for the Preparation Thereof - The present invention relates to a process for the preparation of oxymethylene polymers as well as oxymethylene polymers obtainable therefrom. The process includes polymerization of a monomer, which forms —CH | 03-31-2011 |
| 20090283931 | Molded Bodies Containing Polyacetals and Method for Producing Said Molded Bodies - The present invention relates to moldings encompassing polyacetals, where the molding has a microcellular structure. The moldings have excellent mechanical properties. Furthermore, the moldings have very little tendency toward stress cracking. Processes for production of inventive moldings are also disclosed. | 11-19-2009 |
| 20090200153 | Method for producing and dehydrating cyclic formals - Processes are described which comprise: (a) providing a mixture comprising a cyclic formal and water, wherein the mixture has a cyclic formal concentration and a water concentration; (b) bringing the mixture into contact with an aqueously selective membrane; (c) creating a pressure differential across the membrane; and (d) obtaining a permeate having a higher water concentration and a lower cyclic formal concentration than the mixture, and a retentate having a lower water concentration and a higher cyclic formal concentration than the mixture. | 08-13-2009 |
| 20090111932 | THERMOPLASTIC PARTIALLY CRYSTALLINE MOLDING COMPOUND HAVING A REDUCED SURFACE LUSTER AND PRODUCTS MADE THEREFROM - The present invention relates to novel molding compositions based on semicrystalline engineering thermoplastics which, in conventional processing techniques, give moldings with reduced surface gloss. A feature of the molding compositions is that they comprise, in a polymer matrix, if appropriate with the usual additives, polymer particles with a median size d | 04-30-2009 |
| 20080287580 | COLORED POLYOXYMETHYLENE MOLDING COMPOUNDS AND MOLDED PARTS PRODUCED THEREFROM - The present invention relates to a polyoxymethylene molding composition comprising

| 20080272052 | Method for Producing and Dewatering Cyclic Formals - Processes are described which comprise: (a) providing a mixture comprising a cyclic formal and water, wherein the mixture has a cyclic formal concentration and a water concentration; (b) bringing the mixture into contact with an organically selective membrane; (c) creating a pressure differential across the membrane; and (d) obtaining a permeate having a lower water concentration and a higher cyclic formal concentration than the mixture, and a retentate having a higher water concentration and a lower cyclic formal concentration than the mixture. | 11-06-2008 |
| 20080242800 | LOW-EMISSION COLORED POLYOXYMETHYLENE MOLDING COMPOSITION - Colored molding compositions made from polyacetal copolymer, where the polyacetal copolymer essentially consists of oxymethylene units and oxyethylene units, and a strong protonic acid was used as initiator during preparation of the polyacetal copolymer, have lower formaldehyde emission than that from a comparable molding composition for which the polyacetal copolymer was prepared using a Lewis acid as initiator. The formaldehyde emission is generally less than 20 mg/kg, preferably less than 10 mg/kg. | 10-02-2008 |
