摘要
A polyester/polycarbonate blend having superior thermal stability and superior color stability is disclosed. The polyester/polycarbonate blend comprises: (a) P(ET-CT) (poly(ethylene terephthalate-co-1,4-cyclohexylene dimethylene terephthalate) which is copolymerized with 1,4-cyclohexanedimethanol (CHDM) of 40 to 90 mol % with respect to total diol components; (b) polyethylene terephthalate (PET); (c) polycarbonate (PC); and (d) germanium of 1 to 100 ppm (weight ratio) with respect to total polyester/polycarbonate blend, wherein with respect to total polyester/polycarbonate blend, the amount of the P(ET-CT) and PET is 50 to 90 weight%, the amount of the PET is 1 to 6 times in weight ratio with respect to the P(ET-CT), and the amount of the PC is 10 to 50 weight%.
