  • Publication number: 20120232236
    Abstract: This invention relates to a supported nonmetallocene catalyst and preparation thereof. The supported nonmetallocene catalyst can be produced with a simple and feasible process and is characterized by an easily controllable polymerization activity. This invention further relates to use of the supported nonmetallocene catalyst in olefin homopolymerization/copolymerization, which is characterized by a lowered assumption of the co-catalyst as compared with the prior art.

  • Publication number: 20120226006
    Abstract: The invention relates to a novel polymerization method for (meth)acrylates, wherein the polymerization is initiated by isocyanates and special bases having an imine structure. By means of said novel method that can be deliberately employed, even high-molecular-weight poly(meth)acrylates having in part a narrow molecular weight distribution can be produced. Furthermore, a wide variety of polymer architectures, such as block, star or comb polymers, are available using said novel polymerization method.
