SUSTAINABLE POLYESTER POLYOL COMPOSITIONS

Polyester polyol compositions are disclosed. The polyol compositions, which comprise recurring units of a digested thermoplastic polyester, a glycol, and castor oil, ricinoleic acid, or a mixture of castor oil and ricinoleic acid, have hydroxyl numbers within the range of 20 to 150 mg KOH/g and aver...

Beschreibung
Zusammenfassung:	Polyester polyol compositions are disclosed. The polyol compositions, which comprise recurring units of a digested thermoplastic polyester, a glycol, and castor oil, ricinoleic acid, or a mixture of castor oil and ricinoleic acid, have hydroxyl numbers within the range of 20 to 150 mg KOH/g and average hydroxyl functionalities within the range of 2.5 to 3.5. The invention includes flexible polyurethane foams that incorporate the polyester polyols. Sustainable polyester polyols made completely or in substantial part from recycled, post-industrial, and/or biorenewable materials such as polyethylene terephthalate, glycols, and castor oil are provided. The polyols have desirable properties for formulating flexible polyurethane foams and other products. L'invention concerne des compositions de polyester-polyol. Les compositions de polyol, qui comprennent des motifs récurrents d'un polyester thermoplastique digéré, un glycol et de l'huile de ricin, de l'acide ricinoléique ou un mélange d'huile de ricin et d'acide ricinoléique, présentent des indices d'hydroxyle situés dans la plage de 20 à 150 mg de KOH/g et des fonctionnalités hydroxyle moyennes situées dans la plage de 2,5 à 3,5. L'invention comprend des mousses souples de polyuréthane qui incorporent les polyester-polyols. L'invention concerne également des polyester-polyols durables fabriqués entièrement ou en partie substantielle à partir de matériaux recyclés, post-industriels et/ou biorenouvelables, tels que le poly(téréphtalate d'éthylène), les glycols et l'huile de ricin. Les polyols présentent des propriétés souhaitables pour la formulation de mousses souples de polyuréthane et d'autres produits.
