摘要: 利用热分析研究了聚对苯二甲酸乙二醇酯(PET)与对苯二甲酸乙二醇酯(ET)-己内酯(CL)共聚物(TCL)共混体系的相容性,同时考察了体系中TCL组成分布不均一性及高温热处理对体系相容性的影响。

Abstract: The miscibility of the blends of polyethylene terephthalate(PET) with ethylene terephthalate-caprolactone random copolyesters(TCL)was examined by DSC, and a miscibility limit concerning ET content in the TCL copolyesters was obtained. The effects of ET contents in the TCL and the transesterification occurred at elevated temperature on the miscibility of the blend system are discussed.

Key words: PET, copolyester, blend, miscibility
