摘要
通过原子转移自由基聚合（ATRP）合成了聚丙烯酸叔丁酯-b-聚（4-乙烯基吡啶）嵌段共聚物（PtBA60-b-P4VP50），并用核磁共振（1HNMR）、红外光谱（IR）和凝胶渗透色谱（GPC）封嵌段共聚物进行了表徵，确定了嵌段共聚物的结构。PtBA-b-P4VP在碱性条件下水解得到同时含有阴阳离子的新型嵌段共聚物（P4VP5-一b—P（Aa46-CO—tBA16）。通过激光光散射和透射电子显微镜等研究了PtBA60—b—P4VP50和P4VP50-b—P（Aa46-CO—tBA16）在选择性溶剂中的自组装行为，选择性溶剂的性质封自组装膠束的形态结构具有显着的影响。
In this thesis, poly （tert-butyl acrylate）-b-poly （4-vinyl pyridine） （PtBA-b-P4VP） ionic block copolymers were synthesized by using atom transfer radical polymerization （ATRP） and characterized by NMR, PTIR, GPC. The nature of selective solvent influenced the diameter of PtBA60-b-P4VP50 micelle evidently. Block copolymer PtBA60-b-P4VP50 can self-assemble into core-shell micelle in selective solvent tetrahydrofuran （THF）, ethyl acetate and n-hexane. Di-ionic block copolymer P4VPso-b-P （AA46-co-tBA16） can self-assemble into aggregates in aqueous solutions with pH 2 and pH 11. The hydrodynamic diameter of the aggregrates was 230.2 nm and 167.1 nm, respectively.
