PBT films treated at various temperatures for different periods of time were studied by FTIR
WAXD
elementary analysis and the mechanical property measurement. The heattreat-ment promoted the ring-closing reaction to completion
and the molecular chain regularity
the length of the conjugated system in the polymer chain were improved. The mechanical properties and the thermal stability of the PBT films were obviously increased. The best condition for heat-treating was also given.
