摘要:
设计NaX分子筛负载低毒稀土氧化物和钛酸四丁酯为复合催化剂,成功合成出聚丁二酸丁二醇酯(PBS).探讨熔融缩聚法、溶液-熔融结合法,以及其反应条件对所合成的PBS相对分子质量的影响,确定最佳合成条件为220 ℃,缩聚3 h,可以合成出质均相对分子质量为17.8万的PBS.通过核磁、红外光谱,凝胶渗透色谱和热分析仪对合成的PBS进行表征和测试.结果表明:目标产物确认为PBS,具有良好的热稳定性.
Abstract:
Poly(butylene succinate)(PBS)was synthesized with a new catalyst of NaX molecular sieve-supported ligand Nd2O3/Ti(OC4H9)4 by polycondensation. The synthetic methods, including melt polycondensation and solution-melting method, as well as the reaction conditions were investigated on the PBS molecular weight. The weight-average molecular weight of PBS was about 178 000 under the synthesis conditions of 220 ℃ and 3 h condensation. The product was further characterized by 1H NMR spectroscopy, infrared spectroscopy, gel permeation chromatograph and thermal analyzer. The results showed that the synthetic product was PBS with a good thermal stability.
