20100193988 | DEGASSING EXTRUDER FOR DEGASSING A POLYMER MATERIAL AND METHOD FOR DEGASSING A SYRUP CONSISTING OF POLYMERS, SOLVENTS AND/OR MONOMERS USING A DEGASSING EXTRUDER - The invention relates to a vented extruder ( | 08-05-2010 |
20110017439 | HEAT EXCHANGER FOR HEATING TEMPERATURE AND RESIDENCE TIME SENSITIVE PRODUCTS - The invention relates to a tube bundle heat exchanger for transferring heat for the temperature sensitive and/or polymerisible substances. Said heat exchanger comprises a housing ( | 01-27-2011 |
20110028663 | STIRRED-TANK REACTOR AND METHOD FOR CARRYING OUT A POLYMERISATION REACTION USING SAID TYPE OF STIRRED-TANK REACTOR - The invention relates to a stirred-tank reactor and to a method for carrying out a polymerisation reaction of unsaturated monomers using a stirred-tank reactor. According to the invention, said stirred-tank reactor is characterised in that the product discharge point is designed as the central base outlet that is at least partially traversed by the agitator shaft. Said polymerisation is performed continuously under positive pressure, so that the stirred-tank reactor is operated hydrodynamically. | 02-03-2011 |
20110188336 | DRIVE ARRANGEMENT IN A DEGASSING EXTRUDER - The invention relates to a vented extruder ( | 08-04-2011 |
20110263806 | COPOLYMER FOR PRODUCING MOLDED BODIES THAT ARE DIMENSIONALLY STABLE UNDER HEAT FROM MOLDING COMPOUNDS OR CAST GLASS - The invention relates to a copolymer for producing molded compounds or cast glass for the production of molded bodies having increased dimensional stability under heat, obtainable from the copolymerization of A) one or more ethylenically unsaturated ester compounds of the formula (I), where R | 10-27-2011 |
20120172563 | HOMOPOLYMERS AND COPOLYMERS OF HYDROXYISOBUTYRIC ACID (ESTER) (METH)ACRYLATES - The invention relates to novel poly(meth)acrylates for producing moulding compositions. In particular, the invention relates to novel methacrylates having ester groups which, in the cleavage process, liberate at most only a very small amount of components which are not re-copolymerizable. Copolymerization of monomers of this type in the production of the novel poly(meth)acrylates for moulding compositions brings about only minimal alteration of the heat resistance of these materials or may indeed improve the same. | 07-05-2012 |
20120232222 | METHOD FOR PRODUCING 1-ALKOXY-2-METHYL-1-OXOPROPAN-2-YL (METH)ACRYLATE - The invention provides a process for preparing 1-alkoxy-2-methyl-1-oxopropan-2-yl(meth)acrylate, e.g. 1-methoxy-2-methyl-1-oxopropan-2-yl(meth)acrylate, by transesterifying alkyl α-hydroxyisobutyrates. Copolymerization of such monomers in the preparation of poly(meth)acrylate-based moulding materials improves the heat distortion resistance thereof. | 09-13-2012 |
20130079439 | COMPOSITE MATERIAL MADE OF A MATERIAL CONTAINING CELLULOSE AND A PLASTIC MATERIAL - The invention relates to novel composite materials which are made of at least one material containing cellulose, preferably wood, and at least one plastic material, and which have improved mechanical and weather resistance properties. | 03-28-2013 |
20130096237 | COMPOSITE MATERIAL MADE OF A MATERIAL CONTAINING CELLULOSE WITH PMMA AS A PLASTIC MATRIX USING DIFFERENT COUPLING COMPONENTS - The invention relates to novel composite materials with improved mechanical properties and improved weathering resistance, said composite materials being made of at least one material containing cellulose, preferably wood, and at least one plastic, and to a method for producing said composite materials and for using same. | 04-18-2013 |
