摘要

利用受控阴离子聚合法合成了一系列线性高分子量丙烯腈均聚物。实验证明，通过控制无金属引发剂和水的浓度，可以生产出分子量范围很广的聚丙烯腈。所得到的均聚物具有极佳的可纺性。

Molecular weight and spinnability of polyacrylonitrile: control with water and 1,8-diazabicyclo[5.4.0]undec-7-ene during anionic polymerization in dimethyl sulfoxide

A series of linear high molecular weight acrylonitrile homopolymers have been synthesized using controlled anionic polymerization. The possibility of producing polyacrylonitrile with a wide range of molecular weights by controlling the concentrations of metal-free initiator and water has been demonstrated. The resulting homopolymers exhibit excellent spinnability.

期刊介绍： Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
