Abstract: Processes and facilities for using one or more PET-containing materials as a feedstock to a chemical recycling facility, and in particular a solvolysis facility, are provided herein. The PET-containing materials used as feedstock may comprise a quantity of PET-containing dry fines. The PET-containing dry fines may be derived from various processes and facilities, including PET reclaimer facilities and/or manufacturers of PET articles. For example, the dry fines may be collected from solid-liquid separators and/or dust collectors from processes that include conveying, drying, densification, centrifugation processes, and/or grinding PET-containing plastic material. Such dry fines are generally undesirable or unusable to mechanical PET recycling facilities, and typically are sent to landfills and/or incinerators. However, the processes and facilities described herein make use of the PET and other plastics present in these otherwise undesirable or unusable dry fines.

Abstract: Processes and facilities for using one or more PET-containing materials as a feedstock to a chemical recycling facility, and in particular a solvolysis facility, are provided herein. The PET-containing materials used as feedstock may comprise a quantity of PET and PVC-containing reclaimer flake reject. The PET and PVC-containing reclaimer flake reject may be derived from various plastic reclaimer separation processes, including density separation. Such flake reject materials are generally undesirable or unusable to mechanical PET recycling facilities due to the PVC content, and typically are sent to landfills and/or incinerators. However, the processes and facilities described herein make use of the PET and other plastics present in these otherwise undesirable or unusable flake reject materials.

Abstract: The invention provides (meth)acrylic oligomers prepared from C1-C20 alkyl and C5-C20 cycloalkyl (meth)acrylates, wherein said oligomers have a Mn of about 300 g/mole to about 3,000 g/mole; a Mw of about 700 g/mole to about 6,000 g/mole; a Mz of about 900 g/mole to about 10,000 g/mole. The oligomers may have a Yellowness Index, according to ASTM E313 of less than 2. The oligomers of the invention are useful as tackifiers in adhesive compositions, but also are believed to be useful also in general polymer modification as plasticizers, leveling agents, viscosity reducers (i.e., rheology modifiers), and for increasing solids content in solvent-borne applications of all types with little detrimental impact on viscosity. The invention also provides adhesive compositions and laminate articles coated on at least one side with the adhesive compositions of the invention.

Abstract: Chemical recycling facilities for processing mixed waste plastic are provided herein. Such facilities have the capability of processing mixed plastic waste streams and utilize a variety of recycling facilities, such as, for example, solvolysis facility, a pyrolysis facility, a cracker facility, a partial oxidation gasification facility, an energy recovery facility, and a solidification facility. Streams from one or more of these individual facilities may be used as feed to one or more of the other facilities, thereby maximizing recovery of valuable chemical components and minimizing unusable waste streams.
