摘要
本文介绍了端NCO基聚醚的合成方法,并详细地讨论了(NCO/OH)值,浓度、温度、时间等影响因素,给出了端基转化的最佳工艺条件选择范围。图2,表2。
The synthetic methods of the end-group NCO polyether have been introduced in this paper, while at the same time the influencing factors such as (NCO/OH) values, concentrations, temperatures, times, etc. were also discussed in detail. The selection range of the optimum processing conditions for the end-group transform are given.
