摘要 为寻找和拓宽NMP方法可聚合的单体,本文用氮氧自由基(NMP)控制的活性聚合方法,制备了分子量窄分布的嵌段共聚物聚(苯乙烯嵌段N乙烯基2吡咯烷酮)(PSbPVP),用傅立叶变换红外光谱(FTIR)和体积排阻色谱(SEC)对其进行表征,发现NMP方法除了可以控制苯乙烯单体,还可以控制NVP单体。通过动态激光光散射(DLS)研究了嵌段共聚物PSbPVP在选择性溶剂中的自组装行为,发现其形成了较窄粒径分布的大小为109nm的纳米尺度的组装体。 To research and find out more monomers which are proper for NMP polymerization than styrene kind monomers, the block copolymer PSbPVP with low polymerization dispersity was prepared by NMP living polymerization, and characterized by FTIR and SEC. The self-assembly of the block copolymer in selective solvent was studied by DLS, and resulted in nano particle with low dispersity through self-assembly.
