摘　　要：以三氯氧磷、二乙二醇及环氧丙烷为原料,四氯化钛为催化剂,合成了一种新型低聚磷酸酯阻燃剂。讨论了影响反应的主要因素,确定适宜的反应条件为:n(三氯氧磷)∶n(二乙二醇)∶n(环氧丙烷)为1.8∶1∶3.15,反应一温度为20℃,反应时间为3 h,反应二温度为65℃,反应时间为3 h,此时,产品收率为90%。并用红外、核磁及凝胶色谱对其进行了表征。A kind of new oligophosphate flame retardant is synthesized by a modified preparation method using phosphorus oxychloride, diethylene glycol and propylene epoxide as raw materials and titanic chloride as catalyst. The effect of the reaction conditions is investigated. The optimum parameters are shown as follows： 1.8： 1：3.15 of the molar ratio of phosphorus oxychloride, diethylene glycol and propylene epoxide,20℃ of the temperature and 3 hours of reaction time at the first stage of reactions ,65℃ of the temperature and 3 hours of reaction time at the 2nd stage of reactions. The yield can reach 90%. IR, 1HNMR and GPC are used to characterize the structure of the final product.
