| Outline of Final Research Achievements |
An useful anionic polymerization method has been established for preparation of various polymer architectures of well-defined structures. In this method, lithiation of toluene by alkyllithium in the presence of tetramethylethylenediamine (TMEDA) is applied to the tolyl units of poly(p-methylstyrene)s of different polymer architectures to form multifunctional macroinitiators of various polymer architectures. Various polymer architectures of comb-type multibranched polymers to linear molecular brushes, ring molecular brushes or sun-shaped polymers, arborescent-type multibranched polymers have been prepared by taking the advantage of this method. Furthermore, this method has been applied to molecular coating of inorganic fine particles surface with covalently connected polymer layer, which provides an useful method for surface modification of inorganic fine particles.
