  • Polyether-modified polybutadienes and processes for preparation thereof
    Publication number: 20230018204
    Abstract: A process can be used for preparing polyether-modified polybutadienes. The process involves reacting at least one polybutadiene (A) with at least one epoxidizing reagent (B) to give at least one epoxy-functional polybutadiene (C). The at least one epoxy-functional polybutadiene (C) is then reacted with at least one hydroxy-functional compound (D) to give at least one hydroxy-functional polybutadiene (E). The at least one hydroxy-functional polybutadiene (E) is finally reacted with at least one epoxy-functional compound (F) to give at least one polyether-modified polybutadiene (G).
