Abstract

The first aim of this work was to study the solid-state copolymerization (SSP) of bis(2-hydroxyethyl)terephthalate (BHET) with poly(butylene terephthalate) (PBT) by FTIR spectroscopy. The development of the chemical microstructure during the SSP-reaction was examined as a function of the BHET content, showing the different regimes. The thermal behaviour of the resulting copolymers with different BHET contents was also investigated during cooling using infra-red dynamic spectra. For low BHET-concentrations, only crystallization of PBT-sequences was observed, while for high BHET-concentrations, only crystallization of PET-sequences was detectable with a cross-over behaviour for intermediate concentrations.
