FLEXIBLE OR SEMI-FLEXIBLE FOAM COMPRISING A POLYESTER POLYOL

A flexible or semi-flexible foam, or a composition making it possible to obtain a flexible or semi-flexible foam, including a polyester polyol or a polymer comprising a polyester polyol. The polyester polyol is obtained by a first polycondensation (a) of an alcohol sugar Z in C3 to C8 and of two identical or different diacids Y and Y in C4 to C36 and a second polycondensation (b) of the product obtained in (a) with two identical or different diols X and X in C2 to C12.

METHOD FOR PRODUCING POLYESTER POLYOLS AND USE THEREOF IN POLYURETHANE

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.
