摘要
以含氟自由基为引发剂，利用本体聚合或加入一定量的溶剂聚合并进行后处理，合成了（Ｍｗ）为（５．０～９．０）×１０５，转化率达６０％的超高相对分子质量ＰＡＮ。系统地研究了各种实验条件以及不同单体浓度及后处理对聚合结果的影响，对这一新型的引发剂进行了初步研究。
he synthesis and properties of PAN with average molecular weight in range of (5.0￣9.0)×105(Mw) prepared both in bulk and in solvent system polymerization using fluorine contained organic radicals as the initiator were investigated systematically. The effect of different experiment conditions, different monomer concentration and post treatment on polymerization was discussed, and the primary research on the new initiator has been put forward.
