Compositions and methods for making polyesters and articles therefrom |
摘要 |
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. |

1. A process for forming a binder material, comprising:
forming a polyester solution, comprising:
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;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; andadjusting the temperature to a second temperature less than the first temperature;adding a vinyl alcohol containing polymer to the reaction mixture; and adding a cross-linking agent comprising an acrylic polymer, wherein the binder material is free of formaldehyde. |
