报道了用小分子链转移剂（CTA）和大分子链转移剂（macro-CTA）的二元混合物引发均聚物和两嵌段共聚物的聚合自组装。在此体系中，均聚物和嵌段共聚物同时形成，并同时扩链形成聚合物纳米物体。均聚物与嵌段共聚物的摩尔比对聚合物纳米粒子的形貌有显著影响。通过该方法制备了具有高度多孔内部结构的多孔囊泡、多孔纳米球和微米级颗粒。我们预计，这种方法将大大扩大聚合诱导自组装的承诺，为一系列的聚合物纳米物体的合成具有独特的形态。
Polymerization-induced self-assembly of homopolymer and diblock copolymer using a binary mixture of small chain transfer agent (CTA) and macromolecular chain transfer agent (macro-CTA) is reported. With this system, homopolymer and diblock copolymer were formed and chain extended at the same time to form polymer nano-objects. The molar ratio of homopolymer and diblock copolymer had a significant effect on the morphology of the polymer nano-objects. Porous vesicles, porous nanospheres, and micron-sized particles with highly porous inner structure were prepared by this method. We expect that this method will greatly expand the promise of polymerization-induced self-assembly for the synthesis of a range of polymer nano-objects with unique morphologies.
