Patent number: 10611879Abstract: Polyester polyols made from thermoplastic polyesters are disclosed. The polyols can be made by heating a thermoplastic polyester such as virgin PET, recycled PET, or mixtures thereof, with a glycol to give a digested intermediate, which is then condensed with a dimer fatty acid to give the polyol. The invention includes a polyester polyol comprising recurring units of a glycol-digested thermoplastic polyester and a dimer fatty acid. The polyester polyol can also be made in a single step by reacting the thermoplastic polyester, glycol, and dimer acid under conditions effective to produce the polyol. High-recycle-content polyols having desirable properties and attributes for formulating polyurethane products, including aqueous polyurethane dispersions, can be made. The polyols provide a sustainable alternative to bio- or petrochemical-based polyols.Type: GrantFiled: April 15, 2019Date of Patent: April 7, 2020Assignee: RESINATE MATERIALS GROUP, INC.Inventors: Shakti L. Mukerjee, Rick Tabor, Adam William Emerson, Kevin Anthony Rogers, Eric D. Vrabel, Matthew T. Brown, Matthew J. Beatty, Jack Rogers Kovsky, Michael D. Kellerman, Michael Robert Christy

Patent number: 10273332Abstract: Polyester polyols made from recycled polyethylene terephthalate (rPET) and processes for making them are disclosed. The rPET is heated with a C3-C10 glycol reactant to give a digested intermediate comprising glycols and a terephthalate component, which comprises 45 to 70 wt. % of bis(hydroxyalkyl)terephthalates, and preferably lesser amounts of terephthalate dimers and trimers. Treatment of the digested intermediate with activated carbon gives a polyester polyol having a color index less than 20. The polyols have desirable hydroxyl numbers, viscosities, appearance, and other attributes for formulating polyurethane products and are a sustainable alternative to bio- or petrochemical-based polyols.Type: GrantFiled: April 30, 2015Date of Patent: April 30, 2019Assignee: RESINATE MATERIALS GROUP, INC.Inventors: Rick Tabor, Eric D.
