Abstract
Phosphorus-modified polyestercarbonate resins having repeating units of the formula: ##STR1## exhibit improved thermal-oxidative stability compared to polyestercarbonates of the prior art comprised of repeating units I and II only. Such resins are useful for making transparent tough films and molded articles having high stability to thermal-oxidative degradation.
