| Abstract: | Novel acetoacetic ester-terminated polyether was synthesized by the reaction between polyether and diketene.The products were characterized by FT-IR、~1H-NMR and ~(13)C-NMR.Results show that acetoacetic ester-terminated polyether has an enol form tautomer and the tautomer is stable.This new kind of acetoacetic ester-terminated polyether can be used for the synthesis of polyether-imine elastomer which has good mechanical property. |
