Abstract:

以环己酮和苯酚为原料合成高纯度的环己基双酚(BHPC),然后以BHPC、间苯二甲酰氯(IPC)和对苯二甲酰氯(TPC)为单体,采用相转移催化界面缩聚法合成共聚芳酯.用FT-IR、1H NMR、DSC、TGA及力学性能测试等对聚合物的结构和性能进行了表征.研究结果表明:在优化条件下,可制得玻璃化转变温度215.2℃、5;热失重温度480.4℃的环己基双酚型共聚芳酯.该聚芳酯具有良好的耐高温、高的透光率和紫外屏蔽性能.
An improved process of synthesis of 1,1-bis-(4'-hydroxyphenyl)-cyclohexane(BHPC)from cyclohexanone and phenol has been reported in this paper.A novel BHPC-polyarlester(PAR-C)were synthesized by means of interfacial polycodensation of BHPC, terephthaloyl chloride(TPC)and isophthaloyl chloride(IPC), which was catalyzed by the phase transfer catalyst. The copolymers were characterized by fourier transform infrared spectrophotometer(FT-IR), hydrogen nuclear magnetic resonance(H NMR), thermal gravimetric analysis(TGA)and differential scanning calorimetry(DSC). The results showed that the glass transition temperature(Tg)of the copolymers is 215.2 ℃ and the decomposition temperature(Td)at 5% weight loss is 480.4 ℃ and ηinh is 0.69. The PAR-C showed excellent thermal behavior, high light transmittance and the ultraviolet shielding performance
