Abstract: A copolycarbonate optical article comprises a polycarbonate composition including: a copolycarbonate having: 2 to 60 mol % of phthalimidine carbonate units, 2 to 90 mol % of high heat carbonate units, and optionally 2 to 60 mol % of bisphenol A carbonate units. The copolycarbonate has less than 100 ppm of each of phthalimidine, high heat bisphenol, and bisphenol A monomers, and less than 5 ppm of various ions, and is prepared from monomers each having a purity of at least 99.6%. The polycarbonate composition has a glass transition temperature of 200° C. to and a yellowness index of less than 30.

Abstract: A copolycarbonate includes 0.005-0.1 mole percent of sulfur-containing carbonate units derived from a sulfur-containing bisphenol monomer, 2-95 mole percent of high heat carbonate units derived from a high heat aromatic dihydroxy monomer, and 5-98 mole percent of a low heat carbonate units derived from a low heat aromatic monomer, each based on the sum of the moles of the carbonate units; and optionally, thioether carbonyl endcaps of the formula —C(═O)-L-S—R, wherein L is a C1-12 aliphatic or aromatic linking group and R is a C1-20 alkyl, C6-18 aryl, or C7-24 arylalkylene; wherein the sulfur content of the high heat copolycarbonate in the absence of the thioether endcaps is from 5-20 parts per million by weight.

Abstract: Methods for screening molecules or moieties for their ability to crosslink are disclosed. An aromatic carbonate, aromatic ester, or aliphatic ester group is attached to the molecule to mimic the presence of a polymer. A solution of the modified molecule is irradiated, and the first-order kinetic rate constant is measured. If the rate constant is high enough or a threshold amount of the molecule is consumed, a polymer is synthesized using the molecule/moiety as an endcap or co-monomer. The polymer is irradiated, and the increase in crosslink density and the gel formation percentage are determined. These parameters, if high enough, indicate the suitability of the molecule/moiety to act as a crosslinking agent, particularly for polycarbonates. Alternatively, the molecule/moiety may be identified as suitable solely by its first-order kinetic rate constant.

Abstract translation: 公开了用于筛选分子或部分交联能力的方法。 将芳族碳酸酯，芳族酯或脂族酯基团连接到分子上以模拟聚合物的存在。 照射改性分子的溶液，测定一级动力学速率常数。 如果速率常数足够高或分子的阈值被消耗，则使用分子/部分作为端基或共聚单体来合成聚合物。 照射聚合物，确定交联密度和凝胶形成百分比的增加。 这些参数，如果足够高，表明分子/部分适合作为交联剂，特别是聚碳酸酯。 或者，分子/部分可以仅通过其一级动力学速率常数来确定为合适的。

Abstract: The present invention relates to a method for the manufacture of a (co)polycarbonate comprising reacting tetrabromo bisphenol A and optionally one or more bisphenol comonomer(s) with phosgene wherein the tetrabromo bisphenol A contains an amount of tetrabromo bisphenol A dimer of at most 3.0 wt.% based on the weight of the tetrabromo bisphenol A, determined after heat treating the tetrabromo bisphenol A at a temperature of 260° C. for a period of 15 minutes.
