    摘要： A process for the production of a bisphenol comprises reacting a feed comprising a phenol, a ketone and water in the presence of an ion exchange resin catalyst to produce an effluent; determining the para—para bisphenol selectivity of the reaction; and adjusting the concentration of the water in the feed based upon the para—para bisphenol selectivity in the effluent.

    摘要： A thermoplastic composition comprises a polycarbonate, and an aromatic sulfonate compound of formula (Y)m—Ar-(Z-S(O)2—X)n wherein each X is independently a substituted or unsubstituted C1-C20 alkyl, substituted or unsubstituted C1-C20 arylalkyl, substituted or unsubstituted C6-C20 aryl, or substituted or unsubstituted C7-C40 alkylaryl; Z is —O—, or substituted or unsubstituted —(O—C1-20—)w—O—, wherein w is 1 to 20; Ar is a C6-C62 aromatic group; m is 0-3 and n is 3-6; and each Y is independently C1-C20 alkyl, substituted C1-C20 alkyl, C6-C20 aryl, C1-C8 alkyl-substituted C6-C20 aryl, halogen, nitro, C1-C20 alkoxycarbonyl, C1-C20 alkoxy, or C1-C20 acyl, and further wherein a molded article having a thickness of 3.2±0.12 millimeters and consisting of the polycarbonate, aromatic sulfonate compound, and an effective amount of each of a mold-release agent and an antioxidant has, after exposure to a total gamma radiation dose of 83 kGy and when measured according to ASTM D1925-70, an increase in yellowness index (dYI) of less than or equal to 45, when compared to the unexposed molded article. Methods of making the thermoplastic composition, and articles prepared therefrom, are also disclosed.

    摘要： Embodiments of ionizing radiation stable polyarylestercarbonate resin compositions, methods for making the ionizing radiation stable compositions, and articles and medical devices made from these ionizing radiation stable compositions are disclosed. For examples the specification discloses a composition which comprises a block copolyarylestercarbonate and a ionizing radiation stablizing additive. The said copolyarylestercarbonate comprises an organic carbonate block and at least one arylate block. The arylate block comprises arylate structural units derived from at least one 1,3-dihydroxybenzene moiety and at least one aromatic dicarboxylic acid moiety. The arylate block has a degree of polymerization of 1 or greater.
