|Outline of Final Research Achievements
This study demonstrated successful examples of one-shot feeding methods for star polymer synthesis. One is based on monomer reactivity difference. In a reaction of a monomer and a less reactive crosslinker, copolymerization proceeded selectively when a reactivity difference was appropriate, yielding a well-defined functional star polymer. The other method is a reaction in a biphasic system, in which the first-stage polymerization proceeded almost exclusively in a common organic solution phase, while the crosslinker was dissolved in the other fluorinated solvent. Vigorous stirring the solution induced nearly quantitative star polymer formation. The resulting star polymers were highly effective for controlling and/or altering surface properties.
