    摘要:
    通过各种方法合成了全氟单体,全氟-2-亚甲基-4-甲基-1,3-二氧戊环(PFMMD)。使用全氟二苯甲酰过氧化物和/或全氟二酯通过自由基机理使单体本体和/或在溶液中聚合。过氧化丁酯作为引发剂。所获得的聚合物(聚(PFMMD))是无色透明的。但是,暴露在大气中的聚合物棒变得浑浊。当通过将聚合物溶液沉淀成氯仿来纯化聚合物时,长时间暴露于空气中它们不会变得浑浊,并且具有很高的紫外线可见光透射率。纯化的聚合物的玻璃化转变温度为130-134°C。NMR测量表明,纯化的聚合物主要具有乙烯基加成聚合物结构。然而,我们假设原始聚合物包含通过开环聚合反应形成的结构单元。聚(PFMMD)样品的分子量可以使用四氯化碳,四溴化碳和磺酰氯作为链转移剂进行调节。在这些调节剂存在下的聚合反应的特征在于非降解链转移。聚(PFMMD)样品的特性粘度在六氟苯中测定。六氟苯是聚(PFMMD)的热力学上好的溶剂。聚(PFMMD
