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.
报道了使用小分子链转移剂（CTA）和大分子链转移剂（macro-CTA）的二元混合物进行均聚物和二嵌段共聚物的聚合诱导自组装。在该体系中，均聚物和二嵌段共聚物同时形成并扩链，以形成聚合物纳米物体。均聚物和二嵌段共聚物的摩尔比对聚合物纳米物体的形态有显著影响。通过该方法制备了多孔囊泡、多孔纳米球以及具有高度多孔内部结构的微米级颗粒。我们期望该方法将极大地拓展聚合诱导自组装在合成一系列具有独特形态的聚合物纳米物体方面的前景。
