We report for the first time the combination of ATRP and ring-opening episulfide polymerization as a means to synthesize polysulfide-based low-dispersity amphiphilic block copolymers. The most significant finding is the possibility to perform ATRP under mild conditions using poly(propylene sulfide) macroinitiators, apparently without any significant copper sequestration by the polysulfides. Using glycerol monomethacrylate (GMMA) as a hydrophilic monomer, the polymers self-assembled in colloidal structures with a morphology depending on the PS/GMMA ratio, but also probably on GMMA degree of polymerization. We here also present a new AFM-based method to calculate the average number of amphiphilic macromolecules per micelle.
我们首次报道了原子转移自由基聚合（ATRP）和开环环硫聚合的结合，以此来合成基于多硫的低分散性两亲性嵌段共聚物。最显著的发现是，使用聚（丙硫醚）大分子引发剂，在温和条件下进行 ATRP 的可能性，显然多硫化合物没有对铜造成明显的螯合。使用甘油单甲基丙烯酸酯（GMMA）作为亲水性单体，聚合物在胶体结构中自组装，其形态取决于 PS/GMMA 比，但也可能取决于 GMMA 的聚合度。我们还在这里提出了一种新的基于原子力显微镜（AFM）的方法，用于计算每个胶束的平均两亲性大分子的数量。
