Abstract: A rigid foam or composition allowing a rigid foam to be obtained made from polyurethane and/or polyisocyanurate. The rigid foam or composition includes polyols selected from polyester polyols and polyether polyols; the polyols include: 5 to 50% of a polyester polyol A by weight relative to the total weight of the polyols; and a polyol B selected from polyester polyols B and polyether polyols B. The polyester polyol A is of general formula Rx-Ry-Z-Ry′-Rx′ in which Z is a C3 to C8 alcohol sugar chosen from glycerol, sorbitol, erythritol, xylitol, araditol, ribitol, dulcitol, mannitol and volemitol. Ry and Ry′ are diesters of formula —OOC—Cn-COO— in which n is between 2 and 34, and Rx and Rx′ are identical or different C2 to C12 monoalcohols.

Abstract: Disclosed is a method for manufacturing an isocyanurate polyurethane-modified foam, called “PUIR,” including: a) providing an oil or oil mixture at least 50% by weight of the fatty acids having a carbon chain of C18 or more, the fatty acids having an overall iodine number Iiodine of at least 100 g of I2/100 g; b) epoxidating at least 50% of the double bonds in the oil to form the corresponding epoxides; and c) directly reacting, in situ, the epoxides that are obtained above with isocyanate or diisocyanate groups for obtaining corresponding oxazolidone derivatives, without passing through the intermediate formation of polyols obtained from epoxides, in the presence of at least one suitable catalyst and at least one expanding agent, so as to obtain the isocyanurate polyurethane-modified foam “PUIR.” Also disclosed are products, such as rigid insulation material, in particular as a material or panels of rigid insulation for roofing.
