Outline of Final Research Achievements

In this work, precise structure control of acrylic polymers was examined through the anionic polymerization of multi-vinylmonomers.
Consequently, the authors established 1) selective polymerization of one vinyl function of divinylmonomers or cyclopolymerization by the proper selection of polymerization systems, and 2) unprecedented single-step synthesis of star polymers by using the above-mentioned originally developed polymerization systems.
