Title: Initiating Mechanism of the Anionic Polymerization of Methacrylates with <i>t</i>‐BuOK and the Synthesis of ABA Type Triblock Copolymers
Abstract: Back Cover: In article number 1900390, Anna Zheng, Yong Guan, and co-workers report that using t-BuOK as initiator, an ABA-type triblock copolymer (PMMA-b-PLMA-b-PMMA) is synthesized at 0 °C without using any sidereaction inhibitors and the monomer conversion is over 97%, which paves the way for the synthesis of thermoplastic elastomers with full polar monomers and full saturated chains by anionic polymerization.
