Abstract
Copolyester-carbonate resin compositions exhibiting improved processability comprised of (i) at least one copolyester-carbonate resin derived from (a) a carbonate precursor; (b) at least one difunctional carboxylic acid or a reactive derivative thereof; and (c) at least one dihydric phenol wherein the bridging divalent hydrocarbon group connecting the two aromatic residues is represented by the general formula ##STR1## wherein R represents a straight chain alkyl radical containing from 1 to 5 carbon atoms.
