Abstract

Miscibility of blends of polyethylene terephthalate (PET) and polybutylene terephthalate (PBT) has been investigated by differential scanning calorimetry (DSC). The first DSC scans revealed that the blends show two glass transition temperatures (Tg) over the whole composition range. The second DSC scans showed a single Tg. It was found that a single Tg indicates a homogeneous single phase showing that the two components were miscible in the amorphous region. The large difference between the experimental and predicted results was attributed to the reinforcing agents in the blend. Composition-dependent values of Tg, Tm, Tc and Tsc of the blends were determined. The higher the PBT content in the PET-rich region, the lower the miscibility as confirmed by the thermal properties.

      Poly(ethylene terephthalate) (PET) and poly(butylene terephthalate) (PBT) have been known as industrially important polyesters which are widely used as commercial fibers and engineering plastics [1]. To improve the properties of PET and PBT, their copolymerization and polymer blends are in progress actively [2–7]. However, kinetic approaches to the reactivities of its monomeric forms such as bis(4-hydroxybutyl) terephthalate (BHBT) and BHET with respect to different polycondensation temperatures have been rare.
