Beschreibung
Zusammenfassung:	Polyester materials, methods for making polyesters materials, and uses of the polyester materials in binder materials and articles of manufacture are disclosed. In one embodiment, a process is provided for preparing a polyester solution, including mixing monomers of at least one organic acid containing at least three carboxylic groups and at least one multi-hydroxyl alcohol containing at least three hydroxyl groups to form a reaction mixture, heating the reaction mixture to a first temperature, polymerizing the monomers at the first temperature until reaching an acid value from about 200 to about 400 mg KOH/g, adjusting the temperature to a second temperature less than the first temperature, and forming the polyester solution. The polyester materials may be mixed with cross-linking materials to form binder materials. The binder material may then be used to form articles of manufacture. L'invention concerne des matières à base de polyester, des procédés de fabrication de matières à base de polyester, et des utilisations des matières de polyester dans des matières de liant et des articles de fabrication. L'invention concerne, dans une mode de réalisation, un procédé pour préparer une solution de polyester, comprenant le mélange de monomères d'au moins un acide organique contenant au moins trois groupes carboxyliques et d'au moins un alcool multi-hydroxylé contenant au moins trois groupes hydroxyle pour former un mélange réactionnel, le chauffage du mélange réactionnel à une première température, la polymérisation des monomères à la première température jusqu'à atteindre un indice d'acide d'environ 200 à environ 400 mg de KOH/g, l'ajustement de la température à une seconde température inférieure à la première température, et la formation de la solution de polyester. Les matières de polyester peuvent être mélangées avec des matières de réticulation pour former des matières de liant. La matière de liant peut ensuite être utilisée pour former des articles de fabrication.
