本文报道了活性阴离子聚合机理与聚合诱导自组装（比萨）过程的结合，以及基于活性阴离子聚合的全苯乙烯嵌段共聚物聚（对叔丁基苯乙烯）-b-聚苯乙烯（PtBS-b-PS）的自组装比萨。首先，通过良好控制的分子量（MW）和窄的分子量分布（Mw/Mn < 1.10），成功地证实了所述双比萨的实用性和可控性。随后，研究了PtBS和PS链段的分子量、目标分子量比Mn、PS/Mn、PtBS和重量固含量等关键因素对形态演变的影响，并绘制了相图。
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 (Mw/Mn < 1.10). Subsequently, the effect of key factors, including the MWs of PtBS and PS segments, targeted MW ratio Mn,PS/Mn,PtBS, and weight solids content, on the morphological evolution was investigated, and the phase diagram was finally presented.
