摘要
以过硫酸盐与硫代硫酸钠为引发剂 ,使丙烯酰胺与棉纤维进行接枝共聚 ,研究了过硫酸盐的加入方式和加入量对接枝反应的影响 ,发现采用过硫酸铵与过硫酸钾两种氧化剂、两步加入的办法能够克服体系中氧气的阻聚作用 。
Graft copolymerization of ammonium acrylate onto cotton fibers was studied with persulfate and sodium hyposulfite as initiator. The effect of sequence and dosage of persulfate used as initiator on the graft yield is examined. Firstly adding ammonium persulfate and secondly adding potassium persulfate can overcome counter-polymerization of oxygen and attain very high conversion and graft ratio of monomers.
