Aromatic polycarbonate resins exhibiting improved heat resistance chain terminated with a residue represented by the general formula <IMAGE> wherein: each R is independently selected from monovalent hydrocarbon radicals, substituted monovalent hydrocarbon radicals, or halogen radicals; a represents a whole number having a value of from 1 to 3 inclusive; n represents a whole number having a value of from 0 up to the number of replaceable hydrogen atoms present on the ring carbon atoms of the aromatic nucleus; and each Z is independently selected from radicals represented by the general formulae <IMAGE> wherein R1 is selected from rigid or bulky monovalent hydrocarbon radicals or rigid or bulky substituted monovalent hydrocarbonradicals. The instant resins may be fabricated into molded articles, films, and sheets.
