20120289657 | FUNCTIONAL MATERIALS WITH CONTROLLABLE VISCOSITY - The present invention relates to an innovative method for controlling the viscosity of, for example, adhesives or coating formulations. The method for controlling viscosity allows very rapid thermoplastic curing of a formulation even at room temperature and a significant reduction in the viscosity at higher temperatures, thereby regaining the capacity for simple processing and allowing, for example, the originally bonded substrates to be separated from one another again with ease. A particular aspect in this context is that a plurality of cycles of thermoplastic curing and a significant reduction in the viscosity are possible with the present system. | 11-15-2012 |
20120309895 | FUNCTIONAL MATERIALS WITH REVERSIBLE CROSSLINKING - The present invention relates to an innovative method for the reversible crosslinking of, for example, adhesives or coating materials. The reversible crosslinking method allows very rapid crosslinking even at room temperature and undoing of the crosslinks at higher temperatures, thereby regaining the capacity for thermoplastic processing and allowing the originally bonded substrates to be separated from one another again with ease. A particular aspect in this context is that a plurality of cycles of crosslinking and undoing of the crosslinks are possible with the present system. | 12-06-2012 |
20130172480 | FUNCTIONAL MATERIALS HAVING A CONTROLLABLE VISCOSITY OR REVERSIBLE CROSSLINKING VIA AZA DIELS-ALDER REACTIONS WITH BISHYDRAZONES OR CONJUGATED BIS-SCHIFF BASES - The present invention relates to innovative materials which are reversibly crosslinkable by means of a thermoreversible mechanism and/or whose viscosity is reversibly adjustable. Through the use of bishydrazones or conjugated bis-Schiff bases as diene components in aza-Diels-Alder reactions, functional materials are generated that feature controllable viscosity and/or reversible crosslinking. | 07-04-2013 |
20130289164 | IMPACT-MODIFIED REACTION RESIN - The present invention comprises a novel formulation for marking trafficways, for example roads, which when compared with the prior art have improved mechanical properties and improved heat resistance during curing. The invention also relates to improved reactive resins for other applications than roadmarkings. The present invention in particular relates to reactive resins which comprise core-shell particles. | 10-31-2013 |
20130303678 | MATERIALS HAVING A CONTROLLABLE DEGREE OF CROSSLINKING - The present invention relates to innovative materials which can be crosslinked by means of two different crosslinking mechanisms, the first crosslinking mechanism being an irreversible crosslinking. The second crosslinking mechanism is a thermoreversible mechanism. | 11-14-2013 |
20140121327 | POLYMER POWDER FOR PRODUCING THREE-DIMENSIONAL OBJECTS - The invention relates to the use of a powder made of a polymer, which of two or more components with functionalities suitable for Diels-Alder reactions, or of a powder mixture (dry blend) made of powders respectively of at least one of the reactive components, where these together enter into the Diels-Alder reaction with one another and are capable of a retro-Diels-Alder reaction, in a rapid-prototyping process. | 05-01-2014 |
20140128536 | LOW-ODOUR (METH)ACRYLIC REACTION RESINS - The present invention relates to an innovative (meth)acrylic reactive resin which cures with low odour or odourlessly. The present invention relates more particularly to reactive resins comprising high-boiling, reactive (meth)acrylic monomers from the group of the polar, cyclically substituted esters of (meth)acrylic acid, more particularly glycerol acetal, ketal or carbonate methacrylates. These new components are used as substitutes for MMA, which represents the major part of the odour nuisance in the existing, prior-art reactive resin systems. Using these new components it is possible to obtain resin formulations which have glass transition temperatures similar to, and properties comparable with, MMA-based resins. The innovative reactive resins are able in addition to exhibit more rapid curing than prior-art MMA-based systems. Reactive resins for the purposes of the invention are reactive monomer mixtures or mixtures of monomers and polymers that when used as a 2-component system can be readily cured. | 05-08-2014 |
20140163165 | LOW MOLECULAR WEIGHT PRODUCTS AND USE THEREOF AS REVERSIBLE OR PERMANENT LOW-TEMPERATURE CROSSLINKING AGENT IN DIELS-ALDER REACTIONS - The invention relates to low molecular mass products and to the use thereof as reversible or permanent low-temperature crosslinkers in Diels-Alder reactions. | 06-12-2014 |
20140323001 | PSEUDOTHERMOPLASTIC, SELF-CROSSLINKING COMPOSITES - In the present process, reversibly crosslinking composites or storage-stable prepregs are produced by means of a hetero Diels-Alder reactions (HDA,) for example of PMMA polymers. At slightly elevated temperature, these prepregs can be reversibly decrosslinked again by a retro hetero Diels-Alder reaction so that they become moldable. The back-reaction to products which are again crosslinked or high molecular weight then takes place at room temperature. | 10-30-2014 |
20140323648 | PHOTO-INDUCED CROSSLINKING OF DOUBLE BOND-CONTAINING POLYMERS BY MEANS OF A PERICYCLIC REACTION - The present invention relates to a novel method for photoinduced crosslinking of, for example, adhesives or coating compositions. | 10-30-2014 |
