Abstract
The present invention relates to polyester/polycarbonate blends having improved low temperature impact strength and processability. More particularly, this invention relates to a thermoplastic molding composition containing an aromatic carbonate polymer, a poly(1,4-cyclohexylenedimethylene terephthalate) (PCT) resin, and a copolyester which consists essentially of repeat units from mixtures of isophthalic acid, terephthalic acid and 1,4-cyclohexanedimethanol.
