摘要： A melt method of preparing polycarbonate having a predetermined number average molecular weight and percent endcapping is described. A computerized process model is used to determine the reaction parameters to be employed in order to furnish the product polycarbonate possessing the desired Mn and %EC. Reaction parameters of importance include a suitable starting molar ratio of diaryl carbonate to dihydroxy aromatic compound, the most appropriate reaction time, reaction temperature and pressure ranges. The target polycarbonate is then prepared using reaction parameters indicated by the process model in a reactor which forms an element of the process model. Characteristics of the reactor which may be included in the process model include agitation rate and reflux ratio during the distillative removal of hydroxy aromatic compound formed as a by-product during the polymerization.

摘要： Polycarbonates having a high level of endcapping and containing a low level of Fries rearrangement product are prepared from dihydroxy aromatic compounds, such as bisphenol A, and diaryl carbonates such as diphenyl carbonate in a two stage process involving a tetraalkyl phosphonium carboxylate catalyzed oligomerization of the reactants in a first reaction stage followed by the addition of an alkali metal hydroxide co-catalyst in the second stage of the polymerization reaction. The late addition of the co-catalyst provides improved polymerization reaction rates as judged by higher polycarbonate molecular weights. The amount of alkali metal hydroxide co-catalyst is small thus avoiding the formation of excessive amounts of Fries product. The method has been used to provide Fries product levels between 200 and 800 parts per million in polycarbonates having Mn values between 7,500 and 8,500 Daltons.

摘要： Mixed alkali metal salts of phosphoric acid in combination with a co-catalyst such as tetramethylammonium hydroxide (TMAH) are excellent transesterification catalysts for use in the preparation of polycarbonate from bisphenol A and diphenyl carbonate. The mixed alkali metal phosphate salts were shown by kinetic measurements made on a model system composed of p-tert-octylphenol and bis(p-cumylphenyl) carbonate to be inherently more potent catalysts than salts of phosphoric acid comprising a single alkali metal ion. In addition to providing higher rates of polymerization, the new catalysts were shown to provide polycarbonates containing reduced levels of Fries rearrangement product relative to polymerization reactions catalyzed by conventional catalyst systems such as sodium hydroxide together with TMAH co-catalyst.
