본 발명은 테레프탈산 잔기, 네오펜틸 글리콜(NPG) 잔기, 1,4-사이클로헥산다이메탄올(CHDM) 잔기, 에틸렌 글리콜(EG) 잔기 및/또는 2,2,4,4-테트라메틸-1,3-사이클로부탄다이올 잔기를 특정 조성 범위로 포함하는 코폴리에스터 조성물과 재활용된 PET의 블렌드로부터 제조된 재활용가능한 성형된 물품에 관한 것으로서, 이는 벽이 두꺼우며(>4 mm), 고 수준의 재활용된 PET 함량을 갖고, 저 헤이즈를 가지며, PET 스트림에서 재활용가능하다. The present disclosure relates to recyclable molded articles made from blends of recycled PET and copolyesfer compositions which comprise residues of terephthalic acid, neopentyl glycol (NPG), 1,4- cyclohexanedimethanol (CHDM), ethylene glycol (EG), and/or 2, 2,4,4- tetramethyl-1,3-cyclobutanediol residues, in certain compositional ranges that are thick-walled (>4mm), have a high level of recycled PET content, have low haze and are recyclable in a PET stream.
