摘要: 本文采用原子转移自由基聚合法(ATRP), 设计合成了具有双温度响应性质的新型糖聚合物, 并对其在水溶液中的胶束化行为进行了动态光散射研究. 结果表明, 该系列糖聚合物具有双温度响应区间, 并且在水中形成表面呈正电性的胶束, 因此可望将其作为带负电的生物大分子(如单链DNA等)的新型载体.

Abstract: Since the existence of sugar groups, glycopolymers can mimic the biological functions of glycolipids and glycoproteins. Recent developments in precision polymerization have made it possible to design glycopolymers of controlled structure and chemical composition. Glycopolymers exhibit sophisticated functions have attracted more and more attentions. Novel glycopolymers containing polyelectrolyte were successfully synthesized by atom transfer radical polymerization. The architectures of the glycopolymers were confirmed by 1H NMR and GPC. DLS and zeta-potential tests were also performed to investigate the solution properties of the glycopolymers. We found that the novel glycopolymers exhibit multi\|temperature responsive property.

Key words: Glycopolymer, Temperature-responsibility, Polyelectrolyte, Zeta potential
