| 20090023851 | PROCESS FOR THE PRODUCTION OF AN ELECTRICALLY CONDUCTING POLYMER COMPOSITE MATERIAL - Process for the production of an electrically conducting carbon nanotube polymer composite material with reduced surface resistance, in which carbon nanotubes are dispersed in a polymer melt in a twin-shaft screw extruder to form a mixture, and the mixture is then extruded. | 01-22-2009 |
| 20090118394 | PROCESS FOR THE PRODUCTION OF IMPACT-MODIFIED FILLED POLYCARBONATE COMPOSITIONS - The present invention relates to a process for the production of impact-modified filled polycarbonate compositions and molding compositions. A process of the present invention involves: (i) mixing the CNT (component C) with rubber-containing vinyl copolymer (component B) and/or rubber-free vinyl copolymer (component D) on a twin screw extruder, to obtain a CNT masterbatch, (ii) mixing the CNT masterbatch with polycarbonate (component A) and optionally with Component B and/or Component D and optionally with an additive on a twin screw extruder. A polycarbonate composition prepared according to the present invention does not experience degradation of the molecular weight of the polycarbonate during compounding a compared to processes known in the art. | 05-07-2009 |
| 20110075511 | METHOD FOR CONSTRUCTING CO-ROTATING, CONTIGUOUS BODIES AND COMPUTER PROGRAM PRODUCT FOR CARRYING OUT SAID METHOD - The invention relates to a method of constructing elements which wipe each other during corotation about two parallel axes in such a manner that they constantly touch each other at at least one point. | 03-31-2011 |
| 20110096617 | Screw Elements for Extruding Plastic Compositions - The invention relates to novel screw elements for multi-screw extruders with screw profiles co-rotating in pairs and being fully self-wiping in pairs, to the use of the screw elements in multi-screw extruders and to a process for extruding plastic compositions. | 04-28-2011 |
| 20110110183 | Method for Constructing Co-Rotating Contiguous Bodies and Computer Program Product for Carrying Out Said Method and Screw Elements Produced Accordingly - The present invention relates to a method of generating tightly intermeshing, self-cleaning, co-rotating screw profiles, the use of the screw profiles in screw and transition elements, novel screw profiles which have been generated by the method and a computer program product for executing the method in a computer system. | 05-12-2011 |
| 20110112255 | Single-Flighted Screw Elements With a Reduced Tip Angle - The invention relates to screw elements for multi-screw extruders with screws co-rotating in pairs and being fully self-wiping in pairs, to the use of the screw elements in multi-screw extruders and to a process for extruding plastic compositions. | 05-12-2011 |
| 20110141843 | SCREW ELEMENTS WITH REDUCED SWEEP ANGLE - The present invention relates to screw elements for multiscrew extruders with pairs of co-rotating and fully wiping screws, to the use of these screw elements in multiscrew extruders and to a method of generating screw elements according to the invention. | 06-16-2011 |
| 20110158039 | Screw Elements with Improved Dispersing Action and Low Energy Input - The present invention relates to new screw elements for multi-screw extruders with pairs of co-rotating and fully wiping screws. | 06-30-2011 |
| 20110160381 | METHOD FOR EXTRUDING PLASTIC MASSES - The invention relates to a process for extruding plastic compositions. The process in particular relates to the conveying, kneading and/or mixing of plastic compositions, in particular of polymer melts and mixtures of polymer melts, above all thermoplastics and elastomers, particularly preferably polycarbonate and polycarbonate blends, also with the incorporation of other substances such as for example solids, liquids, gases or other polymers or other polymer blends. | 06-30-2011 |
