Abstract

A találmány tárgya eljárás poliéterpoliolok előállításáraalkilénoxidnak aktív hidrogénatomot tartalmazó starter vegyületretörténő poliaddícionálásával DMC-katalízis mellett, oly módon, hogy aDMC- katalizátort egy inert szuszpenziós szerben felveszik, és aszuszpenziós szer és az alkilénoxid együttes mennyiségre vonatkoztatva1-30 tömeg% alkilénoxiddal aktiválják 20-200 °C közötti hőmérsékleten,majd egy starter/alkilén-oxid-elegy adagolásával felépítik apoliéterpoliolt.
