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

A process for producing a polyester polyol comprising reacting a recycle stream selected from recycled PET carpet, carpet fiber, containers, textiles, articles or mixtures thereof, with a glycol in a reactor, thereby forming a digested product stream comprising polyols, and an undigested stream; and then reacting the digested product stream with a hydrophobe selected from dimer fatty acids, trimer fatty acids, oleic acid, ricinoleic acid, tung oil, corn oil, canola oil, soybean oil, sunflower oil, bacterial oil, yeast oil, algae oil, castor oil, triglycerides or alkyl carboxylate esters having saturated or unsaturated C-Cfatty acid units, saturated or unsaturated C-Cfatty acids, alkoxylated castor oil, saturated or unsaturated C-Cdicarboxylic acids or diols, cardanol-based products, recycled cooking oil, branched or linear C-Cfatty alcohols, hydroxy-functional materials derived from epoxidized, ozonized, or hydroformylated fatty esters or acids, or mixtures thereof.

Integrated process for treating recycled streams of PET and PTT

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 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.

Integrated process for treating recycled PET and PTT materials

An stable ethylsilicate polymer having a dynamic viscosity of 10 centipoises (cps) to 1,000 cps at 25&#xb0; C. and 50 wt % to 60 wt % silica (SiO). The stable ethylsilicate polymer includes not greater than 1 wt % of TEOS monomer. The process of forming the ethylsilicate polymer includes a two step addition of catalysts. A hydrolysis catalyst is added initially, for example hydrochloric acid, and a second catalyst is added subsequently, such as phosphonitrilic chloride trimer. The ethylsilicate polymer is used to form MQ resins.
