Outline of Final Research Achievements

Foamed phenol resin is used widely as boarding materials because of its high thermal insulation property, however, recycling process other than thermal recycling was not established because thermosetting resin is stability thermally and chemically. In this study solubilization of foamed phenol resin by the breaking of crosslinking between polymer matrices was attained by using aliphatic alcohol. 1-Heptanol was the best solvent for the solubilization at less than 350 oC. Application of the process is possible to another thermosetting rein involving epoxy resin.

Academic Significance and Societal Importance of the Research Achievements

発泡フェノール樹脂の可溶化反応は、フェノール樹脂の構成マトリックス間の架橋結合が切断されて進行するため、焼却による熱回収に限られていたフェノール樹脂に対し、化学再資源化プロセスの可能性が明らかになった。高分子マトリックス間の架橋結合の切断は、炭素-炭素結合の切断よりも温和な条件で進行し、またエポキシ樹脂でも同様な効果が観察されたことから、ICパッケージやCFRPなど、多様な高分子複合材料への適用拡大が期待できる。
