【摘要】 本文描述了用三溴苯酚经氧化偶联缩合制备聚二溴苯醚的方法。讨论了催化剂、反应温度、反应时间对产率及产物结构的影响。聚合物的~1H-NMR、IR谱图及元素分析、含溴量测定,表明产物为聚二溴苯醚。聚二溴苯醚热稳定性高,与多种耐高温塑料相混容性好,是有应用前景的耐高温阻(?)添加剂。更多还原

【Abstract】 Flame retarding poly（ dibromophenylene oxide） was prepared by oxidative coupling polymerization. The results of ¹H-NMR, IR, elemental analysis and TG data were demonstrated and discussed. The effects of reaction temperature and time and K₃ Fe（CN）₃ concentration on the yield and the structure of the product were discussed.The stability of poly （dibromophenylene oxide） is excellent. The product softens at 220—240℃. The characteristics and applications of this flame retarding polymer are indicated in this paper.更多还原
