2-bis(4-(4-fluorobenzoyl)-phenoxy)-hexafluorocyclobutane and aromatic bisphenols by the aromatic nucleophilic substitution reaction in a polar aprotic solvent. These polymers have good thermal stability up to 341 °C with 10% weight loss in inert atmosphere and good solubility in common organic solvents such as THF, DMAc, DMF and DMSO.
在极性非质子溶剂中,通过芳族亲核取代反应,由1,2-双(4-(4-
氟苯甲酰基)-苯氧基)-六
氟环丁烷和芳族双
酚制备了两种新型的聚芳醚。这些聚合物在高达341°C的温度下具有良好的热稳定性,在惰性气氛中的重量损失为10%,并且在常见的有机溶剂(如THF,
DMAc,
DMF和
DMSO)中具有良好的溶解性。
