Abstract: CRYSTALLITE SUSPENSIONS OF CRYSTALLINE, ETHYLENICALLY UNSATURATED POLYESTERS AND POLYHYDROXYL COMPOUNDS; PROCESS FOR THEIR PREPARATION AND THEIR USE FOR THE PREPARATION OF POLYURETHANE- OR POLYURETHANE GROUP-CONTAINING POLYISOCYANURATE POLYMERS Crystallite suspensions containing from 3 to 70 weight percent of a crystalline, ethylenically unsaturated polyester prepared through condensation polymerization, and having a molecular weight factor per double bond of 154.4 to 408, as the dispersed phase, and from 30 to 97 weight percent of a polyhydroxyl compound having a functionality of from 2 to about 8, a hydroxyl number of from 20 to 800, and a melting point of less than 30.degree.C as the coherent phase are suitable for preparing non-cellular and cellular polyurethane- or polyurethane group-containing polyisocyanurate foams.
