style="text-indent:25px">科思創(chuàng)增強(qiáng)PC的制作方法之酯交換法：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苯酚，提高反應(yīng)程度和分子量。酯交換法需用催化劑，分兩個(gè)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(guò)量，經(jīng)酯交換反應(yīng)，排出苯酚，由苯酚排出量來(lái)調(diào)節(jié)兩基團(tuán)數(shù)比，控制分子量。苯酚沸點(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(wàn)，300℃時(shí)的粘度達(dá)600Pa·s，對(duì)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(wàn)。浙江科思創(chuàng)PC增強(qiáng)阻燃9425價(jià)格</p><p
