标 题 :Activated esters for synthesis of sulfonated telechelic polycarbonates
发明人：BRUNELLE DANIEL J; COLONNA MARTINO; FIORINI MAURIZIO; BERTI CORRADO; BINASSI ENRICO
权利人:GEN ELECTRIC
摘要:A process of making a sulfonated telechelic polycarbonate is described. A dihydroxy compound, a carbonate ester, and an activated ester of a sulfobenzoic acid salt are reacted together. The method results in a sulfonated telechelic polycarbonate which has a high percentage of sulfonated end groups, is soluble, and is transparent.

摘要:Low-particulate dihydric aromatic compounds such as bisphenol-A that can be used in the synthesis of low-particulate polycarbonates are prepared by introducing into a desorber column containing a non-aggregate packing material an adduct of bisphenol and phenol and optionally a stripping gas. The column is maintained at an operating temperature that is sufficiently high and an operating pressure that is sufficiently low such that the adduct is distilled. The stream of phenol and the stripping gas is recovered from the top of the column. A second stream containing bisphenol that is substantially free of added particulate matter is recovered from the bottom of the column. This purified stream of bisphenol-A can further be used in a method of producing optical-grade polycarbonate.

摘要:The invention relates to a process for the pretreatment of material surfaces in order to minimize the interaction between polycarbonate and metal and, in the processing and synthesis of polycarbonate, to obtain a high-quality polymer which in particular does not become discolored and is free of insoluble constituents.

摘要:A poly(arylene ether)-polysiloxane multiblock copolymer is prepared by the reaction of a hydroxy-diterminated poly(arylene ether), a hydroxyaryl-diterminated polysiloxane, and an aromatic diacid chloride. This synthesis overcomes disadvantages of known syntheses of poly(arylene ether)-polysiloxane block copolymers. The poly(arylene ether)-polysiloxane multiblock copolymer is useful for improving the melt processability of poly(arylene ether) compositions.
