    摘要： Extrusion of a mixture of an ester-substituted diaryl carbonate, such as bis-methyl salicyl carbonate, a dihydroxy aromatic compound such as bisphenol A and a transesterification catalyst such as tetrabutyl phosphonium acetate (TBPA) affords polycarbonate having a weight average molecular weight of greater than 20,000 Daltons. The extruder is equipped with one or more vacuum vents to remove by-product ester-substituted phenol. Similarly, a precursor polycarbonate having ester-substituted phenoxy endgroups, for example methyl salicyl endgroups, when subjected to extrusion affords a polycarbonate having a significantly increased molecular weight relative to the precursor polycarbonate. The reaction to form a higher molecular weight polycarbonate may be catalyzed by residual transesterification catalyst present in the precursor polycarbonate, or by a combination of any residual catalyst and an additional catalyst such as TBPA introduced in the extrusion step. Fries rearrangement products are not observed in the product polycarbonates.

    摘要翻译： 酯取代的碳酸二芳基酯如碳酸双甲酯，双酚A等二羟基芳族化合物和乙酸四丁基鏻（TBPA）等酯交换催化剂的混合物的挤出，得到重均分子量大的聚碳酸酯 超过20,000道尔顿。 挤出机配备有一个或多个真空通风口以除去副产物酯取代的苯酚。 类似地，具有酯取代的苯氧基端基的前体聚碳酸酯，例如甲基水杨基端基，当进行挤出时，得到相对于前体聚碳酸酯具有显着增加的分子量的聚碳酸酯。 形成较高分子量聚碳酸酯的反应可以通过存在于前体聚碳酸酯中的残留酯交换催化剂，或者通过任何残余催化剂和另外的催化剂如在挤出步骤中引入的TBPA的组合来催化。 在产品聚碳酸酯中没有观察到薯条重排产物。

    摘要： A method for preparing a polymer-organoclay composite composition comprises combining a solvent and an unexfoliated organoclay to provide a first mixture, wherein the unexfoliated organoclay comprises alternating inorganic silicate layers and organic layers, and has an initial spacing between the silicate layers; exposing the first mixture to an energized condition of a sufficient intensity and duration to increase the initial spacing of the inorganic silicate layers, to provide a second mixture; contacting the second mixture with a polymer composition so that the polymer composition fills at least one region located between at least one pair of silicate layers, wherein the polymer composition is at least partially soluble in the solvent; and removing at least a portion of the solvent from the second mixture, wherein the inorganic silicate layers remain separated by the polymer after removal of the solvent.
