ABSTRACT:
A copolycarbonate-polyester, comprising units of formulawherein at least 60 percent of the total number of R1groups are divalent aromatic organic radicals and the balance thereof are divalent aliphatic or alicyclic radicals; units of formulawherein T is a C7-20divalent alkyl aromatic radical or a C6-20divalent aromatic radical, and D is a divalent C6-20aromatic radical; and units of the formulawherein R2and R3are each independently a halogen or a C1-6alkyl group, R4is a methyl or phenyl group, each c is independently 0 to 4, and T is as described above.
