摘要
以苯酚和含有不同链长的长链脂肪酮作为原料,制备了与双酚A结构相似的双酚单体,并与4,4′-二氟二苯酮共聚,合成了几种含有不同长度脂肪族侧链结构的聚醚醚酮类(PEEKs)聚合物.利用元素分析和核磁共振氢谱(1H NMR)对所合成的双酚单体进行了表征,并用红外光谱(FTIR)、示差量热扫描仪(DSC)、热失重分析仪(TGA)和电子拉力机对所合成的聚合物结构和性能的关系进行了研究.
Two novel types of Bisphenol monomers with different pendant long chains are synthesized and characterized by element analysis and nuclear magnetic resonance（NMR）. Poly（ether ether ketone）s with different pendant long chains are prepared via aromatic nucleophilic substitution reaction from 1,4-bis（4-flu- orobenzoye） benzene and these synthesized bisphenol monomers. FTIR is used to characterize the structure of PEEKs. The thermal properties of the polymers are investigated by DSC and TGA. Due to the existence of pendant long chain in PEEKs, the Tg and the temperature of 5% mass loss decrease. The solubility of the polymer is improved. From these results, the relationships between their structures and properties are well established.
