Here, the periodically grafted linear–hyperbranched copolymers (LHGCs) based on polyethylene (PE) and hyperbranched polyglycidol is synthesized via acyclic diene metathesis polymerization and anionic ring‐opening multibranching polymerization. The chemical composition of LHGCs can be controlled by changing the amount of the initial monomer. For the first time this allows to control the architecture (composition and sequence distribution), in which the run length between adjacent hyperbranched pendants is exact along PE backbone. By comparing with aperiodically grafted analogues, the results clearly show the composition and the sequence distribution of LHGCs is identified as the major factor to influence the thermal stability, crystallinity as well as hydrophilicity.
