Small‐angle neutron scattering (SANS) analysis was performed to investigate the miscibility of blends of metallocene‐catalyzed octene linear low‐density polyethylene (octene‐mLLDPE) and low‐density polyethylene (LDPE). The quantitative SANS analysis found that the blends are miscible in both the melt and the quenched states. Moreover, this analysis confirmed that the radii of gyration of octene‐mLLDPE(D) and LDPE(H) remain unchanged in the quenched state and that the two polymer components cocrystallize via fast crystallization from the melt state.
