PROCESS FOR PRODUCING POLYETHER POLYOL, PROCESS FOR PRODUCING FLEXIBLE POLYURETHANE FOAM, AND SEAT |
摘要 |
To suppress deterioration of mechanical properties of a foam, by using a polyol system solution stored. A polyol system solution is prepared by using a polyether polyol (A1) having a hydroxy value of from 5 to 45 mgKOH/g and an average number of hydroxy groups of from 2 to 8, obtainable by subjecting an alkylene oxide to ring-opening addition polymerization to an initiator, in the presence of a double metal cyanide complex catalyst, to obtain an intermediate polyol; and subjecting ethylene oxide to a ring-opening addition polymerization in an amount of from 1 to 23 mol per 1 mol of the initiator to the intermediate polyol, in the presence of an alkali metal hydroxide as a polymerization catalyst, and a flexible polyurethane foam is produced by using the polyol system solution. |
