    • Hydroxy-functional polyethers having a "cardo" diphenylene group in their backbones are prepared by contacting at least one dinucleophilic monomer with at least one dtglycidyl ether of a cardo bisphenol, such as bis(hydroxyphenyl)fluorene, phenolphthalein, or phenolphthalimidine or a substituted cardo bisphenol, such as a substituted bis(hydroxyphenyl)fluorene, a substituted phenolphthalein or a substituted phenolphthalimidine, under conditions sufficient to cause the nucleophillo moieties of the dinucleophilic monomer to react with epoxy moieties to form a polymer backbone containing pendant hydroxy moieties and ether, imino, amino, sulfonamido or ester linkages. These polyethers possess a combination of high barrier to oxygen transmission (i.e., oxygen transmission rate less than 10.0 cm.sup.3 -mil/100 in.sup.2 -atm-day to oxygen) and high heat resistance (i.e., Tg above 120.degree. C.). These polyethers are suitable for use in the manufacture of retort-sterilizable packaging materials exhibiting high barrier to oxygen.

    • Described is a polycarbonate, polyester, or polyestercarbonate composition prepared from a reaction mixture comprising at least one diol and at least one carbonate precursor or ester precursor, wherein at least about 95 mole percent of the diol present in the reaction mixture consists of one or more aromatic diols, at least about 10 mole percent of which consists of one or more stilbene diols. The composition of the invention advantageously has a relatively high thermal resistance, melting temperature, tensile and flexural properties, and/or resistance to thermal embrittlement. Moreover, the polymers of the invention which are thermotropic liquid crystalline also advantageously possess a broad temperature range for liquid crystallinity, good melt processibility, a low coefficient of thermal expansion, a high ignition resistance, high solvent resistance, and/or good barrier properties.

    • 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.
