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
