PROCESSES FOR THE PRODUCTION OF POLYMER COMPOSITIONS FROM BIO-BASED ETHANOL AND COMPOSITIONS THEREOF

摘要

Methods for producing polyalkylene terephthalate polymer compositions are disclosed. The polymers contain polymer chains having terephthalate containing carbons sourced from bio-based ethanol. Polymer compositions with polymer chains having terephthalate containing carbons sourced from bio-based ethanol include at least two of the carbon atoms in the terephthalate ring derived from the bio-based ethanol. The polyalkylene terephthalate polymers include polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), and polybutylene terephthalate (PBT). The Henkel process can convert ethanol to ethylene oxide, beta propiolactone, terephthalic acid. Combining TPA and monoethylene glycol can produce the polyalkylene terephthalate polymer compositions. Polyalkylene terephthalate polymer compositions are used as plastic molding compositions and as material for manufactured consumer goods packaging, most prominently in plastic water bottles.
