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: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.

标 题 :Polyester Carbonates on the Basis of Cycloaliphatic Diacids, 1,4:3,6-Dianhydrohexitol and Specific Amounts of an Additional Aliphatic Dihydroxy Compound

摘要:The present invention relates to a process for preparing a polyester carbonate on the basis of cycloaliphatic diacids and at least one 1,4:3,6-dianhydrohexitol and at least one additional aliphatic dihydroxy compound, to the polyester carbonate prepared according to the process and to a molding compound and a molding body containing the polyester carbonate. The process according to the invention is a direct synthesis, in which all structural elements forming the subsequent polyester carbonate are present as monomers already in the first process step. It is characterized in that a specific ratio of 1,4:3,6-dianhydrohexitol and the at least one additional aliphatic dihydroxy compound is advantageous.
