ABSTRACT:
Alternating copolyestercarbonate resins having repeating units of the formula: ##STR1## wherein R.sup.1 is meta-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 and exhibit physical properties such as impact strength and processability that are superior to the comparable properties of corresponding alternating copolyestercarbonates wherein R.sup.1 is para-phenylene. Such resins are useful for making transparent tough films and molded articles having high heat resistance.
