摘要： A process for the preparation of poly(arylcarbonate)s, relying on reaction of dialkyl carbonates with bisphenols and using selected organotin and oganotitanium catalysts. The process is preferably performed in a first step in which bisphenols and dialkyl carbonates are reacted using a catalyst to obtain an oligo(arylcarbonate). The oligo(arylcarbonate) then undergoes a post polycondensation in a second step, either by itself or with diphenyl carbonate. The second step also uses a catalyst. The process yields poly(arylcarbonate)s that are characteristically free of color and gel.

摘要翻译： 一种制备聚（芳基碳酸酯）的方法，其依赖于碳酸二烷基酯与双酚的反应，并使用选定的有机锡和催化剂。 该方法优选在使用催化剂反应双酚和碳酸二烷基酯以获得低聚（芳基碳酸酯）的第一步骤中进行。 然后，寡（芳基碳酸酯）在第二步中经由本身或与碳酸二苯酯进行后缩聚反应。 第二步也使用催化剂。 该方法产生特征上没有颜色和凝胶的聚（芳基碳酸酯）。
