中文摘要：

基于超分散剂的构思，设计合成了一类以脲基为桥基的染料聚醚衍生物，并探讨其对母体分散染料的分散和应用性能。试验结果表明，合成的超分散剂对其母体分散染料具有较好的分散效率，自制的分散体系应用性能可达到或优于商品染料，其中RL彻的分散效率较其它3种染料聚醚衍生物（RL100，RL200和RL300）更高，可使染色废水的COD值降低至传统商品分散染料的1／10—1／20。

英文摘要：

Based on the conception of hyper-dispersant, the urea-linked dye-polyether derivatives were designed and synthesized, and the dispersing and application performance for the parent dye were also explored. The results indicated that the new dye-polyether derivatives could significantly improve dispersing efficiency for the parent dye particles, and application performance of self-made dye dispersions could be reached or better than that of commercial dye. Among them, the dispersion efficiency of RL207 was higher than other three kinds of dye-polyether derivatives （ RL100, RL200 and RL300）. With the novel system, the COD value of the dyeing effluents was 1/10 - 1/20 of that byusing commercial dye.
