We report the combination of the living anionic polymerization (LAP) mechanism with the polymerization-induced self-assembly (PISA) process, and the all-styrenic diblock copolymer poly(p-tert-butylstyrene)-b-polystyrene (PtBS-b-PS) based LAP PISA. Firstly, the practicability and controllability of the LAP PISA were successfully confirmed by the well-controlled molecular weight (MW) and narrow molecular weight distribution (M_w/M_n < 1.10). Subsequently, the effect of key factors, including the MWs of PtBS and PS segments, targeted MW ratio M_n,PS/M_n,PtBS, and weight solids content, on the morphological evolution was investigated, and the phase diagram was finally presented.

利用活性阴离子聚合机理的全苯乙烯纳米物体的聚合诱导自组装过程

我们报告了活性阴离子聚合（LAP）机理与聚合诱导的自组装（PISA）过程的结合，以及全苯乙烯二嵌段共聚物聚（p-叔丁基苯乙烯）-b-聚苯乙烯（P t BS- b -PS）基于LAP PISA。首先，通过良好控制的分子量（MW）和窄分子量分布（M _w / M _n <1.10），成功地证实了LAP PISA的实用性和可控制性。随后，关键因素的影响，包括P t BS和PS段的MW，目标MW比M _n，PS / M _{n，P t研究了BS}，重固体含量对形态的影响，最后给出了相图。
