本論文主要探討分子鏈主幹上(backbone)含有螺結雙茀單位的芳香族聚醚醯胺。我們使用由9,9´-螺結雙茀所合成出的2,2´-雙(對-酸基苯氧基)-9,9´-螺結雙茀為新的雙酸單體,此螺結雙醚酸單體與數種雙胺單體進行聚合聚醚醯胺高分子。在這螺結體中,兩個由雙茀連結所形成的環,互相垂直。由於高分子主鏈上擁有扭結的雙茀(bifluorene)部分,所以在室溫下對一般溶劑有優異的溶解度;另外,這些新的聚合物也擁有高的熱穩定性。聚醯胺高分子的玻璃轉移溫度(Tg)在234∼306 ℃之間,而裂解溫度(Td;10 ﹪weight loss)在535∼593 ℃之間。
The synthesis of aromatic poly(ether amide)s having spirobifluorene unit in the polymer backbone is described. 2,2´-Bis(p-carboxyphenoxy)-9,9´-Spirobifluorene was used as a new monomer, which was synthesized starting from 9,9'-spirobifluorene. In the spiro-segment, the two fluorine units were orthogonally arranged. This ether linked spiro diacid monomer was employed in reacting with various aromatic diamines to furnish poly(ether amide)s by direct polycondensation. All the synthesized polymers exhibited excellent solubility in common organic solvents at room temperature and possess high thermal stability, attributed to the presence of kinked bifluorene segments along the polymer chain. The glass transition temperatures and the 10 ﹪weight loss temperatures of polyamides were observed at the range of 234∼306 ℃, and 535∼593 ℃。
