  • CATALYST SYSTEMS FOR CRYSTALLIZABLE REACTOR GRADE RESINS WITH RECYCLED CONTENT
    Publication number: 20220372217
    Abstract: The present disclosure relates to a catalyst system to produce crystallizable polyester compositions which comprise residues of terephthalic acid, neopentyl glycol (NRG), 1,4-cyclohexanedimethanol (CHDM), ethylene glycol (EG), and diethylene glycol (DEG), in certain compositional ranges having certain advantages and improved properties including recyclability. The present disclosure also relates to a catalyst system to produce crystallizable polyester compositions which comprise residues of recycled terephthalic acid, recycled neopentyl glycol (NRG), recycled 1,4-cyclohexanedimethanol (CHDM), recycled ethylene glycol (EG), and/or recycled diethylene glycol (DEG), in certain compositional ranges having certain advantages and improved properties including recyclability.
