摘要
综述了近年来碳纤维用聚丙烯腈(PAN)合成工艺的研究进展,介绍了均相溶液聚合、水相悬浮聚合和水相沉淀聚合等传统聚合方式的特点和不足。详细阐述了可逆加成断裂链转移自由基聚合(RAFT)新型聚合工艺,展望了新型工艺在碳纤维用PAN合成中的应用和未来发展方向。
The recent research progress of polyacrylonitrile（ PAN） synthesis for carbon fiber is reviewed,the characteristic and the deficiency about traditional way of polymerization,such as homogeneous solution polymerization,the water phase suspension polymerization and precipitation polymerization are expounded. A new polymerization process named reversible addition fragmentation chain transfer radical polymerization（ RAFT） is elaborated. The application and the future development direction of this new technology in the synthesis of PAN for carbon fiber is prospected.
