A series of ethylene terephthalate--caprolactone copolyesters (TCL) with different hard segment contents were synthesized and characterized by GPC, NMR, and DSC. The analysis from high-field 1 H-NMR reveals that the transesterification between ET and CL segments during synthesis is unavoidable, so T
