Zusammenfassung:The present invention relates to a polyetherester polyol synthesized by reactants comprising a) aromatic acid or aromatic anhydride or the mixture thereof and b) OH-functional starter molecules which comprise alcoholamine or amine-initiated polyether polyol. And also rigid polyurethane foams obtained there with and use thereof for insulation used in the appliance application. La presente invención se refiere a un poliol de polieteréster sintetizado por reactivos que comprenden a) ácido aromático o anhídrido aromático o la mezcla de estos y b) moléculas de inicio OH-funcionales que comprenden poliol de poliéter iniciado con amina o alcoholamina. Y también espumas de poliuretano rígido obtenidas de estas y su uso para el aislamiento utilizado en la aplicación de electrodomésticos.
