Abstract

A copolycarbonate-polyester, comprising units of formula

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

wherein T is a C_7-20 divalent alkyl aromatic radical or a C_6-20 divalent aromatic radical, and D is a divalent C_6-20 aromatic radical; and units of the formula

• • wherein R² and R³ are each independently a halogen or a C_1-6 alkyl group, R⁴ is a methyl or phenyl group, each c is independently 0 to 4, and T is as described above. A method of making a copolycarbonate-polyester is also disclosed.
