This invention relates to moldable polycarbonate compositions and in particular to moldable polycarbonates which have ordered, alternating repeating units derived from bis-(3,5-dimethyl-4-hydroxyphenyl)sulfone (TMBS) and 2,2-bis-(4-hydroxyphenyl)propane (Bisphenol A) dihaloformate, or ordered, alternating repeating units derived from bis-(3,5-dimethyl-4-hydroxyphenyl) sulfone (TMBS) dihaloformate and a bisphenol compound such as 2,2-bis-(4-hydroxyphenyl)propane (Bisphenol A). Such polycarbonate exhibit improved hydrolytic stability and also excellent processability in molding applications.

Injection-moldable copolyesters of terephthalate units, ethylene units and a high proportion (e. g. 82-87) mole %) of oxybenzoate units, and cookware made of such copolyesters. Process for making such copolyesters by reacting polyethylene terephthalate with p-acetoxybenzoic acid in a solvent, first at a temperature below 240. degree. C. to product a fragmented polyester, raising the temperature to split off acetic acid, then adding more acetoxybenzoic acid to raise the oxybenzoate content to more than 80 mole %.
