Abstract:

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.

Abstract:

The present invention relates to polyol blends containing a polyol and a polyphenol alkoxylate, i.e. an alkoxylated polyphenol, and coatings prepared from these blends. The polyol blends have the advantage of a low residual polyphenol content and have desirable viscosity characteristics without the need for diluents or solvents which could result in unwanted VOC emissions. In another aspect of the invention, polyester polyols are prepared using polyphenol alkoxyiates. Coatings prepared using these polyol compositions have improved salt spray corrosion resistance, along with a variety of other excellent coating performance properties. Also, the polyols used herein can contain a significant recycle and biorenewable content, making these blends and coatings sustainable alternatives to petroleum based polyol products.

Abstract:

The present invention relates to polyester polyols made from aromatic polyacid sources such as thermoplastic polyesters. The polyols can be made by heating a thermoplastic polyester such as virgin polyethylene terephthalate, recycled polyethylene terephthalate, or mixtures thereof, with a glycol to give a digested intermediate which is then reacted with a digestible polymer, which can be obtained from various recycle waste streams. The polyester polyols comprise a glycol-digested polyacid source and a further digestible polymer. The polyester polyols provide a sustainable alternative to petrochemical or biochemical based polyester polyols.

Abstract:

Sustainable lubricant compositions made from recycled thermoplastic polyesters and other reclaimed or biorenewable reactants and a method of formulating them are disclosed. The lubricant compositions comprise a polyester base oil, which incorporates recurring units from a digested thermoplastic polyester, a low-molecular-weight polyol, and C-Cfatty acid. The base oil has a number-average molecular weight within the range of 300 to 5000 g/mol, a hydroxyl value less than 50 mg KOH/g, and a viscosity at 40 C. less than 5000 cSt. Some of the lubricant compositions comprise the polyester base oil and one or more additives including anti-wear agents, corrosion inhibitors, antioxidants, thickeners, detergents, and the like. The lubricants have properties that rival those of commercial products made from nonrenewable hydrocarbon blends or polyol esters and are useful for many practical applications such as internal combustion engine oils, gear lubrication oils, hydraulic oils, compressor oils, metal working fluids, and lubricating greases.

Abstract:

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.

Abstract:

Polyester polyols, processes for making them, and applications for the polyols are disclosed. In some aspects, the polyols comprise recurring units from a thermoplastic polyester or an aromatic polyacid source, a glycol, and a hydroxy-functional ketal acid, ester or amide. Optionally, the polyols incorporate recurring units of a hydrophobe. The polyols are made in one or multiple steps; in some aspects, the thermoplastic polyester or aromatic polyacid source and the glycol are reacted first, followed by reaction with the hydroxy-functional ketal acid, ester or amide. The resulting polyols have good transparency and little or no particulate settling or phase separation. High-recycle-content polyols having desirable properties and attributes for formulating polyurethane products, including aqueous polyurethane dispersions, flexible and rigid foams, coatings, adhesives, sealants, and elastomers can be made. The polyols provide a sustainable alternative to bio- or petrochemical-based polyols.

Abstract:

Polyester polyols made from recycled polyethylene terephthalate (rPET) and processes for making them are disclosed. The rPET is heated with a C-Cglycol 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.
