  • Publication number: 20140148514
    Abstract: This disclosure relates to an aliphatic-aromatic copolyester of poly(butylene-co-adipate terephthalate) that is prepared from recycled polyethylene terephthalate in the presence of titanium catalyst and a phosphorous containing compound. The copolyester is contaminated with little or no ethylene glycol and/or isophthalic acid, which are artifacts of preparing the copolyester from recycled PET. Advantageously, because there is little or no contamination from ethylene glycol and/or isophthalic acid in the copolyester, there is essentially no depression in the material's melting temperature.
