NOVEL POLYETHERS ON THE BASIS OF 2,3-EPOXYBUTANE AND PROCESS FOR THE PREPARATION THEREOF

A process for preparing polyethers based on cis-2,3-epoxybutane and trans-2,3-epoxybutane, involves reacting at least one starter compound (A) in the presence of a double metal cyanide catalyst (B), with 2,3-epoxybutane (C) and optionally further epoxy monomers (D), to afford at least one polyether...

Zusammenfassung:	A process for preparing polyethers based on cis-2,3-epoxybutane and trans-2,3-epoxybutane, involves reacting at least one starter compound (A) in the presence of a double metal cyanide catalyst (B), with 2,3-epoxybutane (C) and optionally further epoxy monomers (D), to afford at least one polyether (E). The process also optionally involves reacting the at least one polyether (E) with at least one end-capping reagent (F), to afford at least one end-capped polyether (G).
