## Abstract The effect of solvents on the molecular weight of polyacrylonitrile obtained by anionic polymerization with butyllithium was investigated. The molecular weight was found to decrease with increase in the dielectric constant of the solvents or their solvating power in the following order:
In spite of considerable effort, the understanding of the molecular structure of polyacrylonitrile-based fibers is still incomplete. This paper shows that molecular modeling based on molecular mechanics and dynamics can be used to study the molecular structure of polyacrylonitrile-based fibers with
