Hyperbranched polymers (HBPs) comprising polyether and polyacrylate segments are effective for enhancing the performance of polyether and polyacrylate blends. However, this approach is limited by difficulties associated with efficient synthetic strategies and structural modifications. Herein, we develop a strategy for synthesizing HBPs through the copolymerization of epoxides and acrylates, wherein glycidyl acrylate (GA), a bifunctional monomer comprising epoxy and acrylate groups, was added as the branching point. The dinuclear Cr-complex-catalyzed copolymerization of epoxides and acrylates occurred in a monomer reactivity-determined manner. By varying the feed ratio of GA, HBPs with various branching degrees were accessed, attaining HBPs with different molecular weights. Furthermore, the obtained HBPs are effective in promoting the mechanical performances of polyether and polyacrylate blends. Morphological characterization revealed that the incorporation of HBPs into blends improved the microphase fusion of immiscible domains within the blend, highlighting their excellent compatibilization performances.
