SUSTAINABLE POLYOL BLENDS FOR HIGH-PERFORMANCE COATINGS

Polyester polyol blends are disclosed. The blends comprise 70 to 99 wt. % of an aromatic or aliphatic polyester polyol, 0.1 to 10 wt. % of a sugar having an average hydroxyl functionality of 4 to 6 and a melting point less than 125° C., and 1 to 20 wt. % of a glycidyl compound having a boiling point...

More Information
Summary:Polyester polyol blends are disclosed. The blends comprise 70 to 99 wt. % of an aromatic or aliphatic polyester polyol, 0.1 to 10 wt. % of a sugar having an average hydroxyl functionality of 4 to 6 and a melting point less than 125° C., and 1 to 20 wt. % of a glycidyl compound having a boiling point of at least 200° C. at 760 mm Hg. The polyester polyol can be made by glycolysis of a recycled thermoplastic polymer, such as polyethylene terephthalate. The polyol blends are useful for the production of polymeric coatings and other products. Coatings made from blends of the polyester polyols and 0.1 to 10 wt. % of a sugar are also described.
