摘要： A system for continuously treating recycled polystyrene material includes a hopper/densifier configured to feed recycled polystyrene material into the system. An extruder can turn the recycled polystyrene material into a molten material. In some embodiments, the extruder uses thermal fluids, electric heaters, and/or a separate heater. Solvents, such as toluene, xylenes, cymenes, and/or terpinenes can aid in generating the molten material. The molten material can be depolymerized in a reactor and a catalyst can be used to aid the depolymerizing. In certain embodiments, the catalyst is contained in a permeable container. In some embodiments, copolymers/monomers are grafted onto the depolymerized material. The depolymerized molten material can be cooled via a heat exchanger. The product can be isolated by extraction, distillation, and/or separation. In some embodiments, the product is treated through filtration and absorption media. In some embodiments, multiple reactors are used.

摘要： A method of upcycling polymers to useful hydrocarbon materials. A catalyst with nanoparticles on a substrate selectively docks and cleaves hydrocarbon chains forming shorter hydrocarbon chains. The catalyst includes metal nanoparticles, such as monometallic nickel or ruthenium nanoparticles or a plurality of nanoparticles of two or more metals, on a metal oxide substrate.

摘要： The disclosure provides a method for producing low molecular weight polytetrafluoroethylene containing less C6-C14 perfluorocarboxylic acids or salts thereof. The method for producing low molecular weight polytetrafluoroethylene includes: (1) irradiating high molecular weight polytetrafluoroethylene to provide low molecular weight polytetrafluoroethylene having a melt viscosity of 1.0×102 to 7.0×105 Pa·s at 380° C.; and (2) irradiating the low molecular weight polytetrafluoroethylene to a dose that does not decompose the low molecular weight polytetrafluoroethylene.

摘要： Methods for processing LLDPE recyclates including, but not limited to, polyethylene and polypropylene and compositions therefrom are provided. LLDPE recyclate can be visbroken to improve processing characteristics and/or devolatilized to remove waste byproducts to produce processed LLDPE recyclates. Processed LLDPE recyclates are compounded with pre-consumer polyolefins to produce blend compositions having acceptable or even improved processing characteristics. Such pre-consumer polyolefins can also be visbroken to further tailor processing characteristics of such polymer blends. A combination of extruders and/or extruder zones can be used at the same or different locations for visbreaking and/or compounding of both LLDPE recyclate and/or pre-consumer polyolefins.
