The present invention relates to a process for the treatment of a composition comprising thermoplastics comprising introducing the composition into a reactor under reduction of oxygen content of the atmosphere, heating the composition in the presence of a solvent to liquefy the thermoplastics, separating insoluble fractions and recovering the liquefied thermoplastics which process is conducted with an aliphatic hydrocarbon as solvent.

Catalytic compositions and processes for depolymerizing polyolefin-based feed into useful petrochemical products are described. The compositions are a composite of a zeolite catalyst component and a co-catalyst comprising an activated clay component and/or a solid base component. These catalyst systems, along with heat, are used to both increase the depolymerization reaction rate of the feed streams and suppress poisoning effects of impurities that may be present in the polyolefin-based feed. This results in a shorter residence time in the depolymerization unit and more efficient process.

A tandem polyolefin depolymerization-metathesis process and system for converting polymer waste to smaller hydrocarbons, specifically liquid and gaseous products, which subsequently can be modified and used as feeds or co-feeds for making circular products such as circular ethylene and polyethylene. Specifically, the disclosed processes include a tandem depolymerization process step followed by a metathesis process to provide a effluent that can be separated, further processed with a subsequent depolymerization step, or both. The effluents can be supplied to downstream processing units such as a steam cracker or AROMAX? unit thereby providing an efficient method for converting polymer waste into useful circular products. Therefore, these processes and systems can expand the number of usable plastic waste streams and improve the economics of plastic waste recycling.

A nanoporous open-cell foam or wick structure and method for production are disclosed. The nanoporous foam or wick structures are produced from, for example, thermoplastic or thermoset polymer gels in which a gelation solvent is removed so as to preserve an expanded monolithic gel structure consisting of intertwined and or chemically crosslinked polymer molecular fibrils. The nanoporous foam or wick may encompass a stand-alone structure, or be incorporated in to microporous open cell foams or wick materials converting them in to nanoporous cellular materials having a bipore structure. Such produced nanoporous polymer materials have unique properties that may be exploited for making high performance capillary pump loop or heat pipe thermal management systems, low-boiloff slosh-less cryogen storage vessels and superior insulation materials for systems operating under ambient and elevated pressure conditions.

For a fiber compound resin composition, a melt-kneading process is performed together with a base resin 1, a dispersant, etc. without performing a pretreatment through wet dispersion for the purpose of defibration treatment and modification treatment of a fibrous filler 2. As a result, each fiber of the fibrous filler 2 is defibrated from end portions in a fiber length direction, while a dispersant component put in at the same time is more selectively adsorbed to defibrated portions 3 at the end portions defibrated and increased in surface area. As a result, hydrophobization of the defibrated portions 3 is promoted as compared to a non-defibrated portion 4, so that a difference in hydrophobicity is formed in the fiber length direction of the fibrous filler 2. Therefore, even when the fibrous filler 2 is added in large amount, a melt viscosity during molding may be lowered without reducing a strength of a molded article.

A coating applied to an article is provided. The coating has an adhesive material, in contact with at least one substrate of the article. The coating has a plurality of high density metal pellets disposed in the adhesive material. The high density metal pellets are in an amount of at least 90% by weight of the total weight percent of the coating, and each high density metal pellet has a diameter of at least 0.04 inch. The coating further has a polymer material. The coating is applied to the at least one substrate of the article to obtain a mass-enhanced, coated article. The coating has a coating thickness of at least 0.25 inch. The coating thickness and the amount of high density metal pellets are sufficient to provide an attenuation of vibration of the coated article and a reduced risk of unwanted ergonomic effects.
