The work presented in this paper deals with the comparative synthesis of diglycidyl ether-based tetrabromobisphenol-A(TBBPA) using both conventional and nonconventional methods in order to explore materials for better industrial applications with respect to effective yield, cost, and time consideration. The conventional method involved the polycondensation of TBBPA and epichlorohydrin in the presence of an alkali catalyst. The nonconventional routes adopted for the synthesis of the material involved ultrasonication, microwave irradiation, and UV light exposure. The Fourier transform infrared spectroscopy spectra of all the synthesized materials of the resin were found to be identical, and the X-ray diffraction analysis showed the material as amorphous. The mechanical studies of the resins revealed that all these resins synthesized by different methods are strong and possess high viscosity. Based on the overall thermal, rheological, and excellent hydrophobic properties, it can serve as an excellent flame retardant.

不同合成方法对卤化环氧阻燃树脂热机械性能影响的比较研究

本文介绍的工作涉及使用传统和非常规方法比较合成基于二缩水甘油醚的四溴双酚 A (TBBPA)，以探索在有效产率、成本和时间考虑方面具有更好工业应用的材料。传统方法涉及TBBPA和环氧氯丙烷在碱催化剂存在下的缩聚反应。该材料的合成采用的非常规途径包括超声处理、微波照射和紫外光照射。发现该树脂的所有合成材料的傅里叶变换红外光谱图是相同的，并且X射线衍射分析表明该材料为非晶态。树脂的机械研究表明，通过不同方法合成的所有这些树脂都坚固且具有高粘度。基于整体的热学、流变和优异的疏水性能，它可以作为优异的阻燃剂。
