Blends of Poly(buty1ene terephthalate), PBT, with Polycarbonate, PC, were studied for a range of molecular weights and blend compositions. Blends were available in PBT/PC compositions &30/20 and 40/60, and with M,,, designated by H (high) or L (low). Samples were prepared by melt crystallization, or
The glass transition temperature of amorphous and fractionated poly(ethylene terephthalate) has been measured by differential scanning calorimetry. The application of the Fox-Flory equation for the range of molecular weights between 37100 and 4500 gives the values of Tg~ =342.4 K and Kg=51200. The l
