Inter-versus intramolecular oligomerization of nitrile groups in polyacrylonitrile

  • Published:
Polymer Bulletin Aims and scope Submit manuscript

Summary

Experimental evidence is presented indicating that intermolecular oligomerization of CN groups (leading to crosslinked structures) takes place, and possibly has an even greater importance than the intramolecular reaction (leading to “ladder polymer”), at higher temperatures. The easy, quasi “built-in” crosslinking upon heat treatment is considered the most significant single feature with regard to making polyacrylonitrile and its copolymers unique among synthetic polymers as a carbon fiber precursor.
