摘要：
A copolycarbonate-polyester, comprising units of formula (I) wherein at least 60 percent of the total number of R1 groups are divalent aromatic organic radicals and the balance thereof are divalent aliphatic or alicyclic radicals; units of formula (II) wherein T is a C7-20 divalent alkyl aromatic radical or a C6-20 divalent aromatic radical, and D is a divalent C6-20 aromatic radical; and units of the formula (III) wherein R2 and R3 are each independently a halogen or a C1-6 alkyl group, R4 is a methyl or phenyl group, each c is independently O to 4, and T is as described above.
