| Abstract: | The polyesterification of polyether synthesized by us and the reactive condition are studied.It's found that the reactive mechanism is acyl-oxygen fission,and that when wolfram-silica acide is used as catalyzer,the suitable reactive temperature is about 110 ℃ and the reactive can be completed in 7 hours.The viscosity and the hydroxy value of the reacting system decline less after polyesterification than before. |
