Abstract:
1. A polymer-dispersed polyol (A1) obtained by polymerizing a vinyl monomer in the presence of the the following polyoxyalkylene polyol (a2): 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 hydroxyl 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 wherein said polyol (a1) is obtained by providing a natural fat/oil having no hydroxyl groups with hydroxyl groups by chemical reaction.
