Outline of Final Research Achievements |
The effect of the number and structure of side chains and diacyl units in the anthraquinone-based polyesters from gallic acid or 3,5-dihydroxybenzoic acid were studied in order to develop the biobased polymers with high thermal stability. The position of side chain on anthraquinone units, the branching position in the side chains, and flexibility of the main chain were found to be the factors to control high-order structure of the anthraquinone-based polyesters from gallic acid or 3,5-dihydroxybenzoic acid.

Academic Significance and Societal Importance of the Research Achievements |
バイオマスプラスチックは、化石資源依存度低減や二酸化炭素排出量削減など持続可能な社会実現において重要な材料であり、より広範囲での利用を目指す上で耐熱性を始めとした材料物性の制御が求められる。本研究課題では天然物に特徴的な置換基の多さに着目し、置換基の数や構造に由来する材料物性への影響を調査したものであり、他の複雑な構造を有する天然物の利用における分子設計に寄与することが期待される。
