专利号:US-6596840-B1 优先权日:1999-07-19 标题 :Method for producing modified polycarbonates 发明人:KRATSCHMER SILKE; HUCKS UWE; BUNZEL LOTHAR 权利人:BAYER AG 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.
