  • NOVEL INITIATION METHOD FOR POLYMERIZING (METH)ACRYLATES
    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.
