Abstract
The compositions disclosed herein comprise blends of polyethyleneterephthalate (PET) having improved impact strength and heat resistance without any sacrifice of other properties such as flexural strength, humidity resistance, low mold shrinkage, etc. These compositions comprise ternary blends of 30-95 percent, preferably 35-95 percent by weight of PET, 1-30 percent, preferably 3-15 percent by weight of an aromatic polycarbonate (PC); and 1-12, preferably 2.5-10 percent of a copolyester of terephthalic acid with ethylene glycol and cyclohexane-1,4-dimethanol.
