摘　　要：利用甲基膦酸二甲酯(DMMP)与聚酯多元醇酯交换反应制备了一种反应型含磷阻燃聚酯醇,系统研究了工艺因素对反应转化率的影响。结果表明:金属钠催化的反应物转化率高于碳酸钾、有机锡、4-二甲氨基吡啶和对甲基苯磺酸的催化;优化的钠用量为0.5%、反应温度为170℃、时间为2.0 h;IR分析表明合成了含磷阻燃聚酯醇。New reactive organophosphorus flame-retardant polyesterols were prepared using transesterification of methylphosphonate（DMMP） with polyester polyols. The effect of process factors on the reaction conversion was studied. Based on a series of experiments, optimized process parameters were that 0.05 g Na as catalyst, the reaction at 170 ℃ for 2.0 hour. The infrared spectrum（IR） analysis showed that the formation of organophosphorus flame-retardant polyesterols.
