    摘要: 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.

    摘要: The present invention relates to an innovative polymerization technique for (meth)acrylates and styrenes, in which the polymerization is initiated by isocyanates and special bases with imine structure and is activated/accelerated by addition of ionic liquids. With this new technique, which can be employed selectively, it is also possible to produce high molecular weight poly(meth)acrylates with in some cases narrow molecular weight distribution.The (meth)acrylate notation here denotes not only methacrylate, such as methyl methacrylate, ethyl methacrylate, etc., but also acrylate, such as methyl acrylate, ethyl acrylate, etc., for example, and also mixtures of both.
