Zusammenfassung:To provide a molded article including recycled polyethylene terephthalate with a reduced level of cyclic trimers compared to a molded article of general-purpose mechanical-recycled polyethylene terephthalate.SOLUTION: The present invention provides a method for producing a molded article that includes component (A): 1-50 mass% of recycled polyethylene terephthalate and component (B): 50-99 mass% of a catalyst-deactivated product of polyethylene terephthalate obtained using a germanium catalyst, assuming the total of the components (A) and (B) to be 100 mass%. An injection molded article thereof has a cyclic trimer level of 0.25 mass% or more and 0.42 mass% or less. Also provided is a molded article produced by the method.SELECTED DRAWING: None 【課題】汎用のメカニカルリサイクルされたポリエチレンテレフタレートの成形体と比較して、環状三量体量が低減された回収ポリエチレンテレフタレートを含む成形体を提供すること。【解決手段】成分(A):回収ポリエチレンテレフタレート1~50質量%と、成分(B):ゲルマニウム触媒を使用して製造されたポリエチレンテレフタレートの触媒失活物50~99質量%とを含み(ただし、前記成分(A)と成分(B)との合計を100質量%とする。)、その射出成形品での環状三量体量が0.25質量%以上0.42質量%以下である成形体の製造方法及び成形体。【選択図】なし
