【Abstract】 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.更多还原
