Maleate polyester polyols and coatings made from the polyols are disclosed. The polyester polyols comprise recurring units of (a) a digested thermoplastic polyester or an aromatic dicarboxylate source; (b) a diol; (c) 5 to 95 mole % of an &#x3b1;,&#x3b2;-unsaturated monomer; and (d) 5 to 95 mole % of adipic acid, succinic acid, or a mixture thereof, where the mole % ranges for (c) and (d) are based on the combined molar amounts of (c) and (d). The polyols have hydroxyl numbers within the range of 25 to 450 mg KOH/g, an average of 0.5 to 2.5 reactive unsaturation sites per molecule, and a viscosity less than 1500 cP at 75&#xb0; C. The polyols are thermally curable or energy-curable. Coatings made from the maleate polyester polyols are also described. Traditional coatings based on polyisocyanates and/or (meth)acrylates can be made, in some cases with improved properties and reduced reliance on the acrylate or isocyanate-based components. Surprisingly, the maleate polyester polyols can also be cured directly using UV to produce coatings under ambient conditions without the need for either acrylic or isocyanate functionality, and this allows coating formulators to reduce cost and more easily achieve regulatory compliance without sacrificing important coating properties. Rigid polyisocyanurate and polyurethane foams produced from the maleate polyester polyols have improved fire retardance.

Sustainable, energy-curable polyester polyols and coatings or rigid foams therefrom

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.

Polyester polyols from thermoplastic polyesters and dimer fatty acids

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.

Recycle-content polyester polyols

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.

Polyester polyols from recycled polymers and waste streams

The presently disclosed and/or claimed inventive concept(s) relates generally to oligomeric reaction products formed by the depolymerization of polyethylene terephthalate polymers and methods thereof. More specifically, the presently disclosed and/or claimed inventive concept(s) relates to oligomeric reaction products formed by the depolymerization of polyethylene terephthalate polymer obtained from, for example but not by way of limitation, waste products, such as beverage containers made from polyethylene terephthalate (PET). The oligomeric reaction products can, in one embodiment, be used as a starting material for polyurethanes. The presently disclosed and/or claimed inventive concept(s) also relates to processes for producing oligomeric reaction products from the depolymerization of polyethylene terephthalate. More particularly, the presently disclosed and/or claimed inventive concept(s) relates to a process of producing oligomeric reaction products of polyethylene terephthalate capable of controlling the removal of byproducts during the reaction. The presently disclosed and/or claimed inventive concept(s) also relates to ultraviolet curable urethane acrylate and polyethylene terephthalate compositions and methods of making and uses thereof.
