摘　　要：在乙烯-四氟乙烯溶液共聚合体系研究中,我们曾编制了一个简易的计算机程序,用于测定二种单体的共聚竞聚率,这一方法计算方便,而且可以避免原先作图法中的误差,结果较为可靠。前文我们报道了四氟乙烯与两个新的全氟烷基乙烯基醚的共聚合反应,并对其中一个新单体——7,7-二氯-3-氧杂-全氟庚烯-1——与四氟乙烯的共聚进行了单体竞聚率的测定。结果表明,这一新的含氟烯醚单体的聚合活性较其它已有报道的同类单体大。The reactivity ratios of tetrafluoroethylene (TFE) and perfluoro-3, 6-dioxa-4- methyl-△~7-octyl sulfonyl fluoride (PFMOS) in solution copolymerization have been determi- ned by graphic methods or a computer program based on a set of low conversion copoly- merization experiments. These data are comparable with the literature reported. Considering the experimental method and data treatment, it provides support to the reactivity ratios of the new perfluoro vinyl ether, 7, 7-dichloro-3-oxa-perfluoroheptene-1, in copolymerization with TFE described in a previous paper.
