본 발명은 테레프탈산, 네오펜틸 글리콜(NPG), 1,4-사이클로헥산다이메탄올(CHDM), 에틸렌 글리콜(EG) 및 다이에틸렌 글리콜(DEG)의 잔기를, 재활용성을 비롯한 개선된 특성 및 특정 이점을 갖는 특정 조성 범위로 포함하는 결정화가능한 폴리에스터 조성물을 제조하기 위한 촉매 시스템에 관한 것이다. 본 발명은 또한 재활용된 테레프탈산, 재활용된 네오펜틸 글리콜(NPG), 재활용된 1,4-사이클로헥산다이메탄올(CHDM), 재활용된 에틸렌 글리콜(EG) 및/또는 재활용된 다이에틸렌 글리콜(DEG)의 잔기를, 재활용성을 비롯한 개선된 특성 및 특정 이점을 갖는 특정 조성 범위로 포함하는 결정화가능한 폴리에스터 조성물을 제조하기 위한 촉매 시스템에 관한 것이다. 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.
