Abstract: The invention relates to storage-stable tris(hydroxyalkyl)isocyanurate polyol dispersions containing (a) from 2 to 70 parts by weight tris(hydroxyalkyl)isocyanurate, (b) from 98 to 30 parts by weight of at least one polyol having a functionality of from 2 to 8 and a hydroxyl number from 20 to 1800, and (c) from 0 to 20 parts by weight of one or more dispersion stabilizers. The dispersions are prepared by dissolving starting components A and B at temperatures in excess of 100 DEG C., in some cases adding a dispersion stabilizer and/or crystallization accelerator, with continuous and step-wise cooling of the mixture while stirring. The products are utilized for the preparation of polyurethane plastics, in particular polyisocyanurate foams containing polyurethane or polyurethane groups.
