POLYACRYLONITRILE-BASED CARBON FIBER PRECURSOR FIBER AND CARBON FIBER PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a polyacrylonitrile-based carbon fiber precursor fiber which can improve a carbonization yield without impairing processability in a carbon fiber production method.SOLUTION: The present invention provides a polyacrylonitrile-based carbon fiber precursor fiber containing a quinone skeleton-containing compound with a boiling point or a sublimation temperature of 200°C or more.SELECTED DRAWING: None
