POLYMER POLYOL AND METHOD FOR PRODUCING POLYURETHANE |
摘要 |
Provided is a polymer polyol which has solved problems, such as clogging in a discharge head and insufficient hardness of a resulting polyurethane foam, occurring in the production of a polyurethane foam by mechanical foaming using a conventional polymer polyol as a raw material. The present invention is a polymer polyol (A) in which polymer fine particles (JR) having an ethylenically unsaturated compound (E) as a constituent unit are contained in a polyol (PL), wherein the (PL) comprises a polyol (a) with which the average number x of moles of ethylene oxide added per active hydrogen atom and the primary hydroxidation ratio y of terminal hydroxyl groups satisfy a specific relationship, and the volume average particle diameter (R) of the (JR) is from 0.1 to 1.5 µm. |
