polyesters was strongly affected by the alkoxy side chains of the DHTAAQ units. Conversely, their thermal decomposition behavior depended on the structure of the dicarboxylate units. The thermal properties of the anthraquinone-based polyesters were influenced by both the dicarboxylate units and alkoxy groups, and their glass transition temperature could be controlled over a wide range (81-308 °C).

为了研究主链和侧链对含蒽醌取代基的聚酯的物理性能的影响,由没食子酸(一种主要成分)制备了两种类型的1,5-二羟基-2,3,6,7-四烷氧基蒽醌(DHTAAQs)水解单宁,并与五种二羧酸二氯化物通过界面聚合反应进行聚合。所制备的聚酯的溶解性受到DHTAAQ单元烷氧基侧链的强烈影响。相反,它们的热分解行为取决于二羧酸酯单元的结构。蒽醌基聚酯的热性质受二羧酸酯单元和烷氧基的影响,并且它们的玻璃化转变温度可以在宽范围内(81-308℃)控制。
