The melting behavior of poly(butylene terephthalate) crystallized isothermally for various times was examined using differential scanning calorimetry. After short crystallization times, the DSC analysis gave two melting peaks, but after longer times, the analysis gave three peaks. The latter triplet

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

A modified mathematical model based on the melting and recrystallization of an initial distribution of melting temperatures satisfactorily predicts the melting behavior of PET in differential scanning calorimetry. The simulated DSC curves produced in this work agreed fairly well not only with experi

Blends of the polyhydroxyether of bisphenol-A (Phenoxy) and a series of ethylene terephthalate (ET)-caprolactone (CL) random copolyesters (TCL) having different ET contents were examined mainly by differential scanning calorimeter (DSC). A miscibility limit specified by the ET content was obtained a

The transesterification of poly(bisphenol A carbonate) (PC) with ethylene terephthalate (ET)-caprolactone (CL) copolyester (TCL) was investigated with highfield 1 H NMR spectroscopy. Under an uncatalyzed condition, ET and CL segments in TCL reacted more easily with PC than the corresponding homopoly
