Title (EN) METHOD FOR PRODUCING POLYESTER POLYOLS AND USE THEREOF IN POLYURETHANE
(FR) METHODE DE PRODUCTION DE POLYOL POLYESTERS ET LEUR UTILISATION DANS LE POLYURETHANE
Abstract:
(EN) The invention relates to 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 comprising such a polyester polyol. The invention also relates to the method for producing said polyester polyols and to the use thereof in foams, adhesives, coatings or elastomers of polyurethane or polyisocyanurate.
(FR) La présente invention concerne un polyol polyester de formule obtenu par une première polycondensation (a) d'un sucre alcool Z en C3 à C8 et de deux diacides Y et Y' identiques ou différents en C4 à C36 et d'une seconde polycondensation (b) du produit obtenu en (a) avec deux diols X et X' identiques ou différents en C2 à C12, le polymère comprenant un tel polyol polyester, la méthode d'obtention de tels polyol polyesters et leur utilisation dans les mousses, adhésifs, revêtements ou élastomères de polyuréthane ou de polyisocyanurate.
