摘要： A method of making polycarbonate includes the steps of forming polycarbonate by a melt transesterification method using an activated diaryl carbonate, and compounding the polycarbonate with a phosphorus-containing compound that has an abstractable proton or hydrolyzable group. The phosphorus-containing compound is compounded with the polycarbonate in an amount sufficient to result in an improvement in the color properties of the polycarbonate as compared to pellets formed from the same polycarbonate without addition of the phosphorus-containing compound.

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 tetrabutylphosphonium 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：碳酸二（甲基水杨基）酯，二羟基芳族化合物如双酚A和酯交换催化剂如四丁基鏻乙酸酯（TBPA）的酯取代的二芳基碳酸酯的混合物的挤出得到重均分子量更大的聚碳酸酯超过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： This invention provides a method for preparing polycarbonates, which utilizes polycondensation catalysts of the formula Cs+An−, wherein An− represents anions such as CH3SO3−, NH2SO3−, C2H2O4−, BF4−, B(C6H5CH3)4−, and CH3C6H4SO3−. We have found that this new class of catalysts provides excellent polymerization rates for the preparation of Bisphenol A polycarbonate from the melt polymerization of diphenyl carbonate and Bisphenol A. Moreover, the catalysts of the invention were found to be very selective in substantially reducing the level of branching side reaction, i.e., formation of Fries product, normally associated with the melt polycarbonate process.

摘要： Polycarbonates, such as bisphenol A polycarbonates, having end groups derived from a di-t-alkylphenol such as 3,5-di-t-butylphenol have very low electrostatic charges. They are thus useful in applications where static charge is a problem, such as automotive headlamps and optical data recording media.

摘要： High flow brominated polycarbonates, useful as flame retardant additives for other polymers such as polyesters, are obtained by equilibration of a brominated aromatic polycarbonate such as a tetrabromobisphenol A homo- or copolycarbonate with a di- or polyhydroxy aromatic compound such as bisphenol A, or a diaryl carbonate, and an equilibration catalyst, under conditions such that the weight average molecular weight of the brominated polycarbonate is reduced by at least 35%. Preferred equilibration catalysts are Group I metal carboxylates, such as sodium stearate, and hexaalkylguanidinium salts.
