Beschreibung
Zusammenfassung:	The invention provides a preparation method of polymer polyol, which comprises the following steps: S100, continuously adding a top material A into a first reaction kettle filled with a bottom material A, and reacting to obtain a first reaction material; s200, continuously adding the first reaction material and the top material B into a second reaction kettle filled with the bottom material B, and reacting to obtain a second reaction material; s300, continuously adding the second reaction material into a third reaction kettle filled with a backing material C for reaction to obtain polymer polyol; wherein the top material A comprises an initiator, a macromonomer, styrene, acrylonitrile and isopropanol, and the bottom material A comprises isopropanol and a macromonomer; the top material B is prepared from an initiator, isopropanol, styrene, acrylonitrile and polyether polyol; the backing material B and the backing material C are the same or different and are respectively and independently polymer polyol.
