是重要的工程塑料。但聚碳酸酯易應(yīng)力開裂，受熱時易水解，加工前應(yīng)充分干燥。聚碳酸酯的制法有酯交換法。（1）酯交換法原理與生產(chǎn)滌綸聚酯的酯交換法相似。雙酚A與碳酸二苯酯熔融縮聚，進(jìn)行酯交換，在高溫減壓條件下不斷排除***，提高反應(yīng)程度和分子量。酯交換法需用催化劑，分兩個階段進(jìn)行：***階段，溫度180—200℃，壓力270—400Pa，反應(yīng)1—3h，轉(zhuǎn)化率為80%—90%；第二階段，290—300℃，130Pa以下，加深反應(yīng)程度。起始碳酸二苯酯應(yīng)過量，經(jīng)酯交換反應(yīng)，排出***，由***排出量來調(diào)節(jié)兩基團(tuán)數(shù)比，控制分子量。***沸點(diǎn)高，從高粘熔體中脫除并不容易。與滌綸聚酯相比，聚碳酸酯的熔體粘度要高得多，例如分子量3萬，300℃時的粘度達(dá)600Pa·s，對反應(yīng)設(shè)備的攪拌混合和傳熱有著更高的要求。因此，酯交換法聚碳酸酯的分子量受到了限制，多不超出3萬。（2）直接法屬于酰氯，活性高，可以與羥基化合物直接酯化。合成聚碳酸酯多采用界面縮聚技術(shù)。雙酚A和***配成雙酚鈉水溶液作為水相，有機(jī)溶液（如***）為另一相，以胺類（如四丁基***化銨）作催化劑，在50℃下反應(yīng)。反應(yīng)主要在水相一側(cè)，反應(yīng)器內(nèi)的攪拌要保證有機(jī)相中及時地擴(kuò)散至界面，以供反應(yīng)。直接法比酯交換法經(jīng)濟(jì)。舟山便宜的PC德國拜耳</p><p
