Front Cover: Janus polymerization is used to synthesize novel branched polytetrahydrofuran and poly(tetrahydrofuran-co-ε-caprolactone) with excellent tensile property and selfhealing behavior. The branched structure was resulted from the dual roles of glycol diglycidyl ether as both initiator and comonomer, supported by both DFT calculation and experimental characterization. This work extended the application of Janus polymerization in designing topological polymers. This is reported by Yao Li, Tianwen Bai, Yifan Li, and Jun Ling* in the article number 1600450.
