The invention relates to a method for producing hydrogenated polyether-modified amino-functional polybutadienes and hydrogenated polyether-modified amino-functional polybutadienes that can be produced by the method, the method comprising the following steps: a) reacting at least one polybutadiene (A) with at least one epoxidation agent (B), to obtain at least one epoxy-functional polybutadiene (C); b) reacting the at least one epoxy-functional polybutadiene (C) with at least one amino-functional compound (D) to obtain at least one hydroxyl-functional and amino-functional polybutadiene (E); c) reacting the at least one hydroxyl-functional and amino-functional polybutadiene (E) with at least one epoxy-functional compound (F) to obtain at least one polyether-modified amino-functional polybutadiene (G); d) hydrogenating the at least one polyether-modified amino-functional polybutadiene (G) in order to obtain at least one hydrogenated polyether-modified amino-functional polybutadiene (H). 本发明涉及一种制备氢化的聚醚改性的氨基官能的聚丁二
