PAN copolymer molecular weight distribution too wide
Fenómeno do problema
Precursor with wide molecular weight distribution causes carbon fiber performance decline
Análise das causas
Improper control of polymerization process conditions (initiator, temperature, chain transfer)
Solução
Optimize polymerization formulation and conditions; control the reaction temperature constant
Conclusão principal
Narrow molecular weight distribution is beneficial to the uniformity of precursor quality
