Abstract: Processes for recovering polyester from feedstocks. The processes can include exposing a feedstock composition to one or more solvents to dissolve at least a portion of the polyester or the non-polyester components. The processes can also include one or more solid-liquid separations to recover the polyester and/or to remove the non-polyester components. The recovered polyesters can also be used in a depolymerization process to recover one or more dialkyl terephthalates or glycols.

Abstract: A continuous flow process and system for depolymerizing plastic. A heterogeneous mixture of plastic particles, a solvent, and a catalyst are pumped continuously through a heating zone at a flow rate just high enough to maintain a particle speed great enough to keep the plastic particles in suspension. The temperature of the heterogeneous mixture is raised in the heating zone and maintained in a hold zone to complete depolymerization of the mixture into a homogeneous solution containing a liquefied reaction product. The homogeneous solution is cooled to solidify and precipitate a solid reaction product. The solid reaction product is separated from the solvent to be recycled. The solvent is recirculated to be reused as a constituent of the heterogeneous mixture.

Abstract: Processes for recovering dialkyl terephthalates. The processes can include exposing a polyester composition to one or more glycols to depolymerization conditions thereby providing one or more depolymerization products. The one or more depolymerization products can be exposed to an alcoholysis process to recover dialkyl terephthalate. Optionally, the one or more glycols can be recycled and re-used in a subsequent dialkyl terephthalate recovery or other process.

Abstract: A molded article providing an electromagnetic shielding, comprising i) a polymer substrate comprising at least one polymer having a contact angle θ with water of at most 95°; and ii) a metal coating coated directly on at least a part of the surface of the polymer substrate by thermal layering. By appropriate selection of polymer substrate, a metal coating can be applied to the surface thereof by thermal layering techniques without the need of a chemical surface pre-treatment or modification, or the application of a primer layer, even if the polymeric substrate contains significant proportions of reinforcing fillers or flame retardants. The invention also relates to a process for manufacturing a molded article providing an electromagnetic shielding, comprising i) providing a polymer substrate comprising at least one polymer having a contact angle θ with water of at most 95°; and ii) directly coating at least a part of the surface of the polymer substrate with a metal coating by thermal layering.
