摘　　要：介绍了偏氯乙烯（VDC）-丙烯腈（AN）乳液聚合的方法，研究了各种助剂及工艺条件对VDC-AN共聚物分子质量的影响，结果表明：当m（VDC）：m（AN）=60：40、反应时间为5-6h时总转化率最高，该共聚物纤维的LOI〉30％，其阻燃性能优良。Methods for the emulsion polymerization of vinylidene chloride（VDC） and acrylo- nitrile（AN） were introduced. Effects of various additives and process conditions on the molecular weight of vinylidene chloride-acrylonitrile copolymer were studied. The results showed that the highest total conversion ratio could be obtained when the mass ratio of VDC to AN was 60 ： 40 and the reaction time was 5-6 hours, and the limiting oxygen index （LOI） of the obtained copolymer fiber was 〉30% and its flame retardant property was good.
