Pre-treating a waste polyester material with dichloromethane (DCM) produce purified polyester for reuse. The purified polyester can be recycled via any chemical or mechanical recycling process. Where the waste polyester material includes non-polyester contaminants, the DCM-treated polyester material produces a slurry that includes the DCM, a solid component that includes a polyester monomer product for reuse, and a waste liquid component where the non-polyester contaminants can be filtered from the top of the liquid component.

Feedstock purification of polyester waste for recycling processes

A waste polyester material is prepared for recycling by dissolving the material in a solution comprising hexafluoroisopropyl (HFIPA) and a chlorinated hydrocarbon, such as dichloromethane (DCM) and/or an aromatic hydrocarbon, such as toluene or xylene, to form a dissolved polyester sample. The dissolved polyester may be prepared for recycling by evaporation, spray drying, and/or precipitation, which produces a purified solid polyester product. The dissolution solution, which is separated from the purified solid polyester product, is also recycled through distillation with purification.

Feedstock engineering of polyester waste for recycling processes

Polyester-free cotton is obtained from a fabric and/or fibers containing polyester and cotton by reacting the fabric and/or fibers with an amine organocatalyst and/or carboxylic acid salt of same and an alcohol solvent. The reaction, which may be run in batches or as a continuous flow process, recovers (i) polyester-free cotton as a solid inert by-product of the reaction, (ii) the amine organocatalyst and/or carboxylic acid salt of same for reuse, (iii) a polyester monomer product, and (iv) unreacted alcohol. The reaction works on any polyester-cotton fabric and/or fibers, including those that have at least one additional material, such as polyethers polyolefins, polyurethanes, nylon, rayon, acetate, viscose, modal, acrylic, wool, and combinations thereof.

Recycling process for the recovery of cotton from polyester-cotton fabrics and/or fibers

A thermally reworkable adhesive includes at least one di-epoxide, at least one diamine that is reactive with the at least one di-epoxide, at least one additive that is miscible, but not reactive, with the at least one di-epoxide and/or the at least one diamine. Reaction of the at least one di-epoxide and the at least one diamine forms a crosslinked polymer network and the at least one additive offsets the stoichiometry of the crosslinked polymer network by 5-50%. The offset crosslinked polymer network forms the thermally reworkable adhesive that once cured, at a temperature in the range of 20-200° C., can be de-bonded from a device to which it is attached at a temperature in the range of 50-200° C.

Thermally reworkable adhesives for electronic devices

Polyester-free magnetic and/or metallic components are obtained from a multicomponent polyester device by reacting the multicomponent polyester device with an amine organocatalyst and/or carboxylic acid salt of same and an alcohol solvent. The reaction recovers (i) the polyester-free magnetic and/or metallic components as solid inert by-products of the reaction, (ii) the amine organocatalyst and/or carboxylic acid salt of same for reuse, (iii) unreacted alcohol for reuse, and (iv) a polyester monomer product. Where the multicomponent device includes a non-polyester material, such as polystyrene, the polystyrene is fully recovered from the reaction. Where the multicomponent polyester device includes recording media, the reaction process sanitizes the inert byproducts of the recording media, thus scrubbing any personal data from the reacted recording media.

Media recycling and sanitization

An asphalt modifier includes bitumen, polyolefin particles, and one or more alkyl terephthalamides. Preparing an asphalt modifier includes combining one or more alkyl terephthalamides, polyolefin particles, and bitumen, and dispersing the polyolefin particles in the bitumen to yield the asphalt modifier. Digesting polyethylene terephthalate includes combining polyethylene terephthalate with an alkylamine or carboxyalkylamine to yield a reaction mixture, and heating the reaction mixture to a temperature between about 20° C. and about 300° C. to yield an alkyl terephthalamide.

Mixed waste plastics compatibilizers for asphalt

Described herein are compositions and methods for the conversion of chlorophyll-derived phytol into useful and economically viable surfactants. The provided compositions utilize the hydrophobic phytol structure and added functional groups to increase hydrophilicity at one end of the molecule.

Phytol-based surfactants and methods therefor

Pre-treating a waste polyester material with dichloromethane (DCM) produces a purified polyester for reuse. The purified polyester can be recycled via any chemical or mechanical recycling process. Where the waste polyester material includes non-polyester contaminants, the DCM-treated polyester material produces a slurry that includes the DCM, a solid component that includes a polyester monomer product for reuse, and a waste liquid component where the non-polyester contaminants can be filtered from the top of the liquid component.

A battery includes a cathode with a metal halide and an electrically conductive material, wherein the metal halide acts as an active cathode material; a porous silicon anode with a surface having pores with a depth of about 0.5 microns to about 500 microns, and a metal on the surface and in at least some of the pores thereof; and an electrolyte contacting the anode and the cathode, wherein the electrolyte includes a nitrile moiety.

Porous silicon anode for rechargeable metal halide battery

A battery includes an anode, an electrolyte including a solvent and at least one ion conducting salt, and a cathode including a metal halide salt incorporated into an electrically conductive material. The electrolyte is in contact with the anode, the cathode, and an oxidizing gas.

Resin compositions made of high-performance polymers blended with molecular glass as rheological modifiers are disclosed. The high-performance polymers include thermoplastics, such as polysulfones, polyimides, poly(ether imides), polyketones, poly(ether ketones), and combinations thereof. The molecular glasses are amorphous, non-oligomeric, and have one or more functional groups that promote miscibility of the molecular glass with the high-performance polymers to produce a resin composition with low melt viscosity. Incorporation of the molecular glasses into the high-performance polymers does not alter the Young's modulus and yield stress values of the high-performance polymers.

Molecular glasses as rheological modifiers in high-performance polymers

Extrudable compositions were prepared comprising poly(propylene) and a liquid additive comprising a lactam group. The compositions can comprise other optional additives that include a polyhemiaminal, antioxidants, UV light absorbers, and surfactants. The extruded compositions have higher percent elongation at break and lower Young's modulus compared to extruded poly(propylene) lacking the liquid additive. These and other property improvements make the extruded compositions attractive for forming field joint coatings for undersea pipeline applications.
