聚四氟乙烯制备

（1）单体四氟乙烯的制备工业上以三氯甲烷为原料，用无水氢氟酸使三氯甲烷氟化，反应温度在65℃以上，用五氯化锑为催化剂，最后用热裂法制成四氟乙烯。也可用锌在高温下与四氟二氯乙烷作用制得四氟乙烯。（2）聚四氟乙烯的制备在搪瓷或不锈钢聚合釜中，以水为介质，过硫酸钾为引发剂，全氟羧酸铵盐为分散剂，氟碳化合物为稳定剂，四氟乙烯经氧化还原聚合而制得聚四氟乙烯。
将各种助剂加入反应釜中，四氟乙烯单体以气相进入聚合釜，调节釜内温度至25℃，然后加入一定量的活化剂（偏重亚硫酸钠），通过氧化还原体系进行引发聚合。聚合过程中不断补加单体，保持聚合压力0.49～0.78MPa，聚合后所得到的分散液用水稀释至一定浓度，并调节温度到15～20℃，用机械搅拌凝聚后，经水洗、干燥，即得本品为细粒状树脂。
