以1，8-二(4-氟苯甲酰基)萘和多种芳香族双酚为原料，合成了无定形、可溶的高相对分子质量聚芳醚酮S[OPhco-napht-COPhOAr]n(Ar=Ph(Me)2Ph，Ph，PhPh，Ph(Tbu)，Ph(CF3)2Ph)。用凝胶渗透色谱(GPC)和核磁共振氢谱(1H、13C)对聚合物进行了表征。用差示扫描量热法测得这些聚合物的玻璃化温度为2 14~2 70℃，在氮气中和空气中的失重率均在476℃和478℃以上，热机械分析的杨氏模数在0.70~4.40 Gpa之间。
High molecular weight, amorphous, soluble poly(arylene ether ketone)s [OPhCO-Napht-COPhOAr] n (Ar= PhC(Me) 2 Ph, Ph, PhPh, Ph(tBu), PhC(CF 3 ) 2 Ph) are synthesized from 1,8-bis(4-fluorobenzoyl)naphthalene and a variety of aromatic bisphenols. The polymers are characterized by GPC and by 1 H and 13 C NMR. The T g 's range from 214 to 270°C, measured by DSC. The 5% weight loss from these polymers by TGA occurs all above 476°C in nitrogen and 478°C in air. Young's moduli are between 0.70 and 4.40 GPa by thermomechanical analysis
