METHOD FOR PRODUCTION OF POLYMER-DISPERSED POLYOL, AND METHOD FOR PRODUCTION OF FLEXIBLE POLYURETHANE FOAM |
摘要 |
To provide a process for producing a flexible polyurethane foam having a higher biomass degree than a conventional flexible polyurethane foam and excellent in foam physical properties and its appearance. A polymer-dispersed polyol obtained by polymerizing a vinyl monomer in the presence of the following polyol (a1) derived from a natural fat/oil and/or the following polyoxyalkylene polyol (a2) is used: Polyol (a1) derived from a natural fat/oil: a polyol derived from a natural fat/oil, which is obtained by providing a natural fat/oil with hydroxy groups by chemical reaction, and which has a hydroxy value of from 20 to 250 mgKOH/g and a molecular weight distribution of at least 1.2; Polyoxyalkylene polyol (a2): a polyoxyalkylene polyol which is produced by ring-opening polymerization of an alkylene oxide (c) with the polyol (a1) derived from a natural fat/oil in the presence of at least one polymerization catalyst (b) selected from the group consisting of a coordination anionic polymerization catalyst and a cationic polymerization catalyst. |
