PURPOSE:To prepare the title compsn. which is lowly viscous and excellent in processability and gives a foam excellent in flame retardance and strengths by compounding an aq. soln. of a saccharide, a specific polyester polyol, a catalyst, and an isocyanate compd. as the essential components. CONSTITUTION:An acid component contg. a compd. having a carboxylic anhydride group and at least one carboxyl group (e.g. trimellitic anhydride), a satd. dibasic acid (e.g. phthalic acid), and, if necessary, an alpha, beta-ethylenically unsatd. dibasic acid is reacted with an alcohol component contg. 5-30 equivalent % (based on the whole alcohol component) tris(2-hydroxyethyl) isocyanurate to give a polyester polyol, which is compounded with an aq. soln. and/or a slurry of a saccharide, a catalyst, an isocyanate compd., and, if necessary, a foam stabilizer, a flame retardant and/or a blowing agent, etc., to give the title compsn. suitable for a building material, etc.
