    摘要： High molecular weight aromatic polycarbonates having molecular weights M.sub.w (weight average) of between about 10,000 and 200,000, which are based on diphenols and monofunctional chain stoppers, which correspond to the general formula ##STR1## in which Z denotes the radical of a diphenol,n denotes an integer from 20 to 400,E denotes ##STR2## m is 0 or 1 and R denotes a hydrogen atom or a C.sub.1 to C.sub.3 alkyl group, and in which between about 0.5 and 5 mol % of Z are radicals of aromatic dihydroxyketones. These polycarbonates share mechanical and thermal properties with known polycarbonates but in addition are suitable for crosslinking, for example in the presence of photoinitiators and optionally photo-reducing agents and under irradiation with UV light. When crosslinked they are resistant to organic solvents and insensitive to stress-cracking, and have particularly good flame-repellent properties when additionally incorporating flameproofing agents.

    摘要翻译： 分子量Mw（重均分子量）在10,000和200,000之间的高分子量芳族聚碳酸酯，它们基于二酚和单官能链终止剂，其对应于通式（I），其中Z表示 二苯酚，n表示20〜400的整数，E表示m为0或1，R表示氢原子或C1〜C3烷基，其中约0.5〜5摩尔％的Z为 芳族二羟基酮。 这些聚碳酸酯与已知的聚碳酸酯共享机械和热性能，但另外适用于交联，例如在光引发剂和任选的光还原剂的存在下，并且在用UV光照射下。 当交联时，它们对有机溶剂具有耐受性并且对应力开裂不敏感，并且当额外加入防火剂时具有特别好的阻燃性能。

    摘要： A single-stage process for the production of pure, particularly sulphur-free, aromatic carboxylic acid chlorides by reacting an aromatic carboxylic acid containing from 1 to 3 carboxyl groups or a corresponding mixture of aromatic carboxylic acids with thionyl chloride in the presence of a catalyst, wherein tertiary phosphine oxides or their reaction products with thionyl chloride and/or the acid chloride to be formed are used as catalysts, and the use of the aromatic dicarboxylic acid dichlorides and tricarboxylic acid trichlorides obtained for the production of polycondensates.
