the monomer MVBP was triggered by the macroinitiator, resulting in a series of triblockcopolymers. The molecular weights and polydispersity indexes were determined by gel permeation chromatography. Differential scanning calorimetry results demonstrate that the triblockcopolymers exhibit twoglasstransitiontemperatures (−120 °C and 160 °C) that are markedly different. As revealed by small‐angle X‐ray
