TRANSESTERIFICATION OF POLY(ETHYLENE TEREPHTHALATE) WITH POLY(ε-CAPROLACTONE)*

Received Date: 14 September 1999

Transesterification of poly(ethylene terephthalate) (PET) with poly(ε-caprolactone) (PCL) was investigated bymeans of NMR spectroscopy, extraction experiments, differential scanning calorimetry (DSC) and phase contrast microscopy(PCM). The 1H-NMR results show that transesterification takes place in the melt blends and leads to the formation of thePET-PCL copolyester with a chemical structure similar to ethylene terephthalate-ε-caprolactonc copolycster (TCL)synthesized directly from monomers.However,even in the blend that has been transesterified for 8 h,the random PET-PCL copolyester,PET-PCL copolyester with long PET or long PCL segments and the unreacted PET and PCL homopolymers may coexist.Due to the low mobility of PET and PCL chains and the high viscosity of the two macromolecules,the transesterification proceeds with difficulty.Furthermore,PET is incompatible with PCL,the transesterirication can only occur at the interface or in the interfacial region between two phases,and finally the reaction can only reach a local equilibrium.These results indicate that in fact the transesterification in the melt blend between two incompatible homopolymers could not lead to the formation of completely random or typical block copolyesters.
