Outline of Final Research Achievements

We have explored novel polymerization designed by chemistry of acylsilane. Its key is the Brook migration of a silyl group. Therein, a repeating unit of silyl enol ether would be produced in the anionic and radical polymerizations of α,β-unsaturated acylsilanes. Such various monomers were examined, and resultantly the anionic polymerization of methacroylsilane was found to conduct the desired migration at a rate of 10~15% along with the normal vinyl polymerization.

Academic Significance and Societal Importance of the Research Achievements

ケイ素は炭素と同族体ではあるが、有機ケイ素化合物は独特の性質や反応性を示すことから、有機化学おいて一つの地位を築いている。本申請研究では、アシルシランの化学に注目し、これまで知られていない高分子合成の新たな方法論を提示することに成功した。しかしながら、時間の関係で重合制御の達成と高分子反応の検討は今後の課題として残った。
