摘要： The present invention relates to a process for producing polycarbonate according to a phase boundary process, from at least one dihydroxydiaryl alkane, phosgene, at least one catalyst and at least one chain terminator, the process allowing a reduction in the phosgene excess by a specific energy input during the dispersion of the aqueous and organic phases. The process also produces a polycarbonate with a low proportion of oligomers and a low proportion of Di-chain terminator carbonate.

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： Processes for increasing the chemical resistance of a surface of a formed article are disclosed. The formed article is produced from a polymeric composition comprising a photoactive additive containing photoactive groups derived from a monofunctional benzophenone. The surface of the formed article is then exposed to ultraviolet light to cause crosslinking of the photoactive additive and produce a crosslinked surface. The crosslinking enhances the chemical resistance of the surface. Various means for controlling the depth of the crosslinking are also discussed.

摘要： Methods for screening molecules or moieties for their ability to crosslink are disclosed. An aromatic carbonate, aromatic ester, or aliphatic ester group is attached to the molecule to mimic the presence of a polymer. A solution of the modified molecule is irradiated, and the first-order kinetic rate constant is measured. If the rate constant is high enough or a threshold amount of the molecule is consumed, a polymer is synthesized using the molecule/moiety as an endcap or co-monomer. The polymer is irradiated, and the increase in crosslink density and the gel formation percentage are determined. These parameters, if high enough, indicate the suitability of the molecule/moiety to act as a crosslinking agent, particularly for polycarbonates. Alternatively, the molecule/moiety may be identified as suitable solely by its first-order kinetic rate constant.
