Beschreibung
Zusammenfassung:	FIELD: polymer production. ^ SUBSTANCE: invention relates to a method of producing polyether-polyols via catalytic addition of at least two alkylene oxides to H-functional initiators, during which operation at least one oxyalkylene unit is incorporated as a result of joint dosage of at least two alkylene oxides. Catalyst utilized is at least one metal cyanide-based compound. When performing joint dosage ratios of alkylene oxides to each other is varied. ^ EFFECT: enabled production of polyether-polyols without clouding and having processing-appropriate viscosity. ^ 8 cl, 12 ex
