标题 :Process for the production of graft polymers
发明人：WENZ ECKHARD; BUCHHOLZ VERA; EICHENAUER HERBERT; WOLF UDO; BORN RALF-JURGEN; JANSEN ULRICH; DIETZ WOLFGANG
摘要:A process of preparing a graft polymer (e.g., an ABS graft copolymer), which involves determining the concentration of at least one reaction component during the course of the reaction by means of Raman spectroscopy, is disclosed. The process, more particularly, comprises: (a) synthesizing the graft polymer from a reaction mixture comprising reactive components (e.g., monomers such as styrene and acrylonitrile, and a graft base); (b) analyzing the reaction mixture, at intervals, during the synthesis of the graft polymer, by means of Raman spectra; (c) recording the results of the Raman spectra analysis; (d) determining the concentration of at least one of said reactive components (e.g., styrene) by means of spectral evaluation of the recorded Raman spectra; and (e) terminating the synthesis reaction of the graft polymer when the concentration of at least one of the reactive components has reached a predetermined concentration value.

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.
