窄分布双酚A聚氧丙烯醚的合成

Synthesis of Narrow Distributed Propoxylated Bisphenol A

以双酚A钠盐(SBPA)为起始剂与环氧丙烷(PO)进行阴离子聚合反应,合成了一种平均PO加合数为10的双酚A聚氧丙烯醚(PBPA)。采用红外光谱和核磁共振谱验证产物结构,并以高效液相色谱分析了产物的相对分子质量分布状态,得到不同催化产物的PO分布指数分别为55.53%(KOH),57.44%(NaOH)和70.62%(SBPA)。实验结果表明,与工业上常用催化剂KOH,NaOH相比,以SBPA为起始剂合成的产物具有较好的PO窄分布性能。

Propoxylated bisphenol A（PBPA） with average PO adducting number 10 was synthesized by anionic polymerization of propylene oxide using sodium bisphenol A（SBPA） as a starting agent.The chemical structure of the product was confirmed by IR spectra and 1HNMR spectra.PO distribution indexes of the PBPA products corresponding to different catalysts were determined by HPLC as follows,55.53%（KOH）,57.44%（NaOH）,and 70.62%（SBPA）.The experimental results showed that the product derived from SBPA had a much better PO narrow-distribution characteristic than the other products catalyzed by industrial catalyst KOH or NaOH.
