摘　　要：利用原子转移自由基聚合技术合成了相对分子质量可控、相对分子质量分布较窄的丙烯酸叔丁酯与氟烷基（甲基）丙烯酸酯的嵌段共取物。进一步将嵌段共聚物的丙烯酸叔丁酯链段在酸性条件下水解，制备了水溶性含氟嵌段共聚物。借助核磁共振氢谱和红外光谱对嵌段共聚物进行了表征。Water-soluble block copolymers containing fluorine were synthesized by atom transfer radical polymerization. The macroinitiator and resulting copolymers were found to exhibit a narrow relative molecular mass distribution. The copolymers were characterized by Fourier transform infrared spectroscopy and nuclear magnetic resonance.
