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 for the synthesis of polycarbonate is disclosed. The process entails reacting in the presence of at least one phosphonium salt as catalyst, at least one diphenol, at least one carbonic acid diester, and at least one alkyl group-substituted phenol chain terminator. The chain terminator is introduced in free form or as a transesterifiable compound under the conditions of the synthesis. The polycarbonate thus produced is suitable for preparing a variety of molded articles.

权利人:SHOWA DENKO KK
摘要:The present invention provides a novel process for the preparation of 5-arylhydantoins as an important intermediate of (D)-arylglycines (e.g., (D)-p-hydroxyphenyl-glycine) useful for the synthesis of semisynthetic penicillines and cephalosporins, the process comprising (i) reacting a 5-unsubstituted hydantoin compound with a halogenating agent and (ii) reacting the resulting product with a p-unsubstituted phenol compound, the hydroxy group of which may be protected, to substitute the 5-position of the hydantoin compound with the phenol compound at the para position.
