摘　　要：为缓解石油资源短缺的问题,基于可再生资源研发新材料,补充或替代石油基材料以达到可持续发展的目的已成为一个新的研究重点.基于对苯二甲酸(PTA)石油基聚合物优异的性能,本文工作利用生物基呋喃双卤单体2,5-双(4-氟苯酰基)呋喃(BFBF)代替PTA,采用高温溶液法与异山梨醇(ISB)和双酚芴(BHPF)共聚合成了一组新型生物基呋喃杂环聚芳醚酮聚合物命名为PIFEKs.并通过核磁共振(NMR)、示差扫描量热分析(DSC)、热失重分析(TGA)等测试方法对PIFEKs的结构和性能进行表征,得到PIFEKs的玻璃化转变温度(Tg)最高为229℃,5%热失重温度(Td,5%)最高为474℃.以上数据表明PIFEKs具有良好的耐热性能,与对应的石油基聚合物性能接近.且溶解性测试结果显示PIFEKs有较为优良的溶解性,该共聚为树脂未来的加工应用提供了更丰富的手段.At present,in order to alleviate the shortage of non renewable resources,developing new materials based on renewable resources to supplement or replace non renewable resources and their derivatives has become a new research focus to achieve sustainable development.As an important high-performance engineering plastic,polyaryletherketone(PAEK)has been successfully commercialized and widely used in many key industries such as aerospace,national defense construction,and electronic information.However,traditional polyaryletherketone raw materials are all derived from petroleum derivatives.Therefore,developing new polyaryletherketones containing biogenic aromatic heterocycles and searching for new polymer materials that can maintain high performance of resins while introducing biogenic groups are methods for alleviating the current problem of non renewable resource shortage of petroleum,and will become one of the effective ways for the sustainable development of polymer materials.Based on the excellent properties of petroleum based polymers such as poly(terephthalic acid)(PTA),a new type of bio based furan heterocyclic polyaryletherketone polymer PIFEKs was synthesized by using 2,5-bis(4-fluorobenzoyl)furan(BFBF)as a substitute for PTA and copolymerizing with isosorbitol and bisphenol fluorene using a high-temperature solution method.And the structure and properties of PIFEKs were characterized by testing methods such as nuclear magnetic resonance,differential scanning calorimetry(DSC),and thermogravimetric analysis(TGA).The highest glass transition temperature(Tg)of PIFEKs was 229℃,and the highest five percent decomposition temperature(Td,5%)was 474℃.The heat resistance improved with the increase of the molar content of bisphenol fluorene monomer.The above data indicates that PIFEKs possess good heat resistance,which is close to the corresponding petroleum based polymer properties.The solubility test results show that PIFEKs have excellent solubility and can dissolve at room temperature in most common organic solv
