PAN copolymer molecular weight distribution too wide
Fenómeno del problema
Precursor with wide molecular weight distribution causes carbon fiber performance decline
Análisis de la causa
Improper control of polymerization process conditions (initiator, temperature, chain transfer)
Solución
Optimize polymerization formulation and conditions; control the reaction temperature constant
Conclusión clave
Narrow molecular weight distribution is beneficial to the uniformity of precursor quality
