摘要
本文用水相沉淀聚合法研完了二过碘酸合银(Ⅲ)络离子[Ag(Ⅲ)]—已酰丙酮氧化还原体系在碱性介质中引发丙烯腈的聚合反应。测定了各种反应条件对聚合反应速率(Rp)和聚合物分子量的影响。探讨了引发反应机理。
The polymerization of acrylonitrile (AN) initiated by diperiodatoargentate(Ⅲ) com-plex-acetylacetone(AA) redox system in agueous alkaline medium was studied.The rate of polymerization(Rp)was determined at different AN concentration , Ag(Ⅲ) concentration, pH value of the medium and temperatures. Meanwhile,the influence of initiator on molecular weight of polymer was measured. Furthermore, based on these experimental results , an initiation mechanism was proposed.
