摘要： Described is a transparent polymer-based composite and a method for preparing a transparent polymer-based composite. The transparent polymer-based composite includes an activated polycarbonate and one or more nanoparticles grafted to the activated polycarbonate. The activated carbonate is formed via a transcarbonation reaction of a mixture of a carbonic acid species having terminal ester groups and a bisphenol-A with sodium hydroxide and ortho-dichlorobenzene. The transparent polymer-based composite may be used to replace the glass front-sheet of solar panels for photovoltaic applications.

摘要： A synthetic resin laminated sheet, in which whitening, cracking, and foaming do not occur when thermoforming is carried out, in particular when deep-draw molding is carried out, and defects do not occur during lamination of a hard coating layer; and a molded article obtained by molding the laminated sheet. A synthetic resin laminated sheet has a coating layer, which includes an acrylic resin, laminated on one surface of a substrate layer including a polycarbonate resin in which a monohydric phenol represented by general formula (1) is used as a chain terminator and is obtained by reacting the monohydric phenol with a dihydric phenol and a carbonate binding agent and has a viscosity average molecular weight of 18000-35000. (In the formula, R1 represents a C8-36 alkyl group or a C8-36 alkenyl group. R2-R5 each represent hydrogen, halogen, or an optionally substituted C1-20 alkyl group or C6-12 aryl group).

摘要： A process for purifying a diaryl carbonate, comprises introducing an aqueous stream to a diaryl carbonate stream that comprises a metal contaminant, wherein the aqueous stream reacts with the metal contaminant to form a precipitate; wherein introducing the aqueous stream to the diaryl carbonate stream results in introducing 100 to 10,000 ppm water based on the total composition of the diaryl carbonate stream and the aqueous stream; removing the precipitate via one or both of a separation column and a filter to result in a purified diaryl carbonate.
