Abstract
The invention relates to a process for preparing an alkoxylated product. The aim of the invention is to provide aromatic polyols for preparing polyurethane-based and polyisocyanurate-based polymers, which ensure good miscibility with the isocyanate component and other components, have a good storage stability and render the end product flameproof. For this purpose, the invention devises a process for preparing an alkoxylated product by. reacting bisphenol F with propylene carbonate and/or propylene oxide as propoxylation agent and ethylene carbonate and/or ethylene oxide as ethoxylation agent, the propoxylation agent and the ethoxylation agent being used in a molar ration of 70:30 to 45:55.
