Patent number: 11718703Abstract: 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.Type: GrantFiled: January 22, 2019Date of Patent: August 8, 2023Assignees: TEREOS STARCH & SWEETENERS BELGIUM, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, SOPREMA, UNIVERSITE DE STRASBOURGInventors: Pierre Etienne Bindschendler, Alexandru Sarbu, Rémi Perrin, Pierre Furtwengler, Luc Avérous, Andréas Redl

Patent number: 11180606Abstract: A polyester polyol of formula produced by a first polycondensation (a) of a sugar alcohol Z in C3 to C8 and two diacids Y and Y? which are the same or different in C4 to C36, and a second polycondensation (b) of the product produced in (a) with two diols X and X? which are the same or different in C2 to C12, the polymer including such a polyester polyol. Also, a method for producing the polyester polyols and the use thereof in foams, adhesives, coatings or elastomers of polyurethane or polyisocyanurate.Type: GrantFiled: August 24, 2017Date of Patent: November 23, 2021Assignees: TEREOS STARCH & SWEETENERS BELGIUM, CENTRE NATIONAL DE LA RECHERCHE SCIEN'I'IFIQUE, SOCIÉTÉ SOPREMA SAS, UNIVERSITÉ DE STRASBOURGInventors: Pierre Etienne Bindschedler, Alexandru Sarbu, Stephanie Laurichesse, Remi Perrin, Pierre Furtwengler, Luc Avérous, Andreas Redl
