| 摘 要： | 为了获得性能优越的碳纤维，聚丙烯腈（ＰＡＮ）纤维已经成为应用最广泛的前驱体之一［１］．事实表明，碳纤维的性能在很大程度上依赖于前驱体纤维的性能［１］，利用丙烯腈与少量其它单体进行共聚，可使聚合物的力学性能（机械强度、弹性、塑性等）得到明显的改善．由已报道的文章可知，与丙烯腈共聚时所采用的其它单体主要有丙烯酸、甲基丙烯酸、丙烯酸酯、丙烯酰胺、衣康酸等［２～７］，所采用的溶剂主要为二甲基甲酰胺（ＤＭＦ）．对在二甲基亚砜（ＤＭＳＯ）为溶剂中的聚合条件，并未见详细报道．本文以ＤＭＳＯ为溶剂，用偶氮二异丁…

| Abstract: | In order to prepare a polymer solution for making carbon fibre precusor by wetspinning,solution polymerization of acrylonitrile ( A N) with itaconic acid ( I A) was carriedoutin D M S Ousing azobisisobutyronitrile ( A I B N) asinitiator. The effects of( A N+ I A) and A I B N concentration , A Nto I Aratio,temperature on conversion rate and molecular weightwere investigated . The polymerization ratein D M S O was 2 .6 time as fast at thatin D M F. The copolymers were characterized by I Rand N M Ranalysis. |
