    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.
