聚三氟氯乙烯树脂的制备方法
摘要：
一种聚三氟氯乙烯树脂的制备方法，属于含氟高分子材料的制备技术领域。其是先对聚三氟氯乙烯纯化处理，然后以去离子水为介质，在表面活性剂的存在下采用引发剂引发三氟氯乙烯聚合反应，得到聚三氟氯乙烯树脂。优点：可将聚合反应的反应时间缩短为＜10h；三氟氯乙烯的转化率达90％以上，所得到的聚三氟氯乙烯树脂耐热性能好，具有良好的可加工性，在240-280℃的加工温度下不会出现降解和变色现象。因此，能适合于工业化生产要求。
摘要（英）：

The invention provides a polychlorotrifluoroethylene resin preparation method, belonging to the technical field of the preparation of fluoropolymer material. The method comprises the following steps:firstly purifying polytrifluorochloroethylene, then adopting deionized water as medium and using initiator to performing chlorotrifluoroethylene polymerization in the presence of surfactant and obtaining polychlorotrifluoroethylene resin. The invention has the advantage that the polymerization reaction time is shortened to less than 10h, the conversion rate of chlorotrifluoroethylene reach above 90%, the obtained polychlorotrifluoroethylene resin has good heat resistance and processability and degradation and metachromatism can not appear under the processing temperature of 240-280 DEG C. Therefore, the method can meet the demand of industrialized production.
