    • Ordered copolyestercarbonate resins having repeating units of the formula: ##STR1## wherein a portion of R.sup.1 is meta-phenylene and a portion of R.sub.1 is para-phenylene and R is independently an aromatic hydrocarbylene or inertly substituted aromatic hydrocarbylene, e.g., ##STR2## exhibit physical properties such as heat resistance, clarity and impact strength that are superior to the comparable properties of corresponding random copolymers. They exhibit melt processability that is superior to the melt processability of corresponding copolyestercarbonates wherein R.sup.1 is entirely para-phenylene. They exhibit heat resistance, notch sensitivity and low temperature impact resistance that are superior to comparable properties of corresponding copolyestercarbonates wherein R.sup.1 is entirely meta-phenylene. Such resins are useful for making transparent tough films and molded articles having high heat resistance.

    • Carbonate polymer compositions are prepared comprising a first diaryl fluorene carbonate polymer component and a second bisphenol A carbonate polymer component, the blend composition preferably comprising from about 1 to about 99 weight percent diaryl fluorene carbonate polymer component based on weight of first and second components. Preferably the first diaryl fluorene carbonate polymer component is a copolymer comprising (a) from about 1 up to and including about 99 mole percent dihydroxyaryl fluorene moiety based on the weight of dihydroxyaryl fluorene compound and additional multihydric monomer compound and (b) moieties of at least one additional condensation copolymerizable multihydric monomer compound remnant. In another embodiment, the invention is an improved process for preparing heat resistant diaryl fluorene carbonate polymer composition comprising the step of combining a first diaryl fluorene carbonate polymer component and a second bisphenol A carbonate polymer component, different from the diaryl fluorene carbonate polymer component. These blends can be prepared by known means such as by solution blending or melt blending. It has surprisingly been found that these blend compositions are miscible and transparent across a range of weight ratios and diaryl fluorene contents.
