Summary: It was found that without additional photoinitiator, methyl methacrylate (MMA) dissolved in common solvent N , N ‐dimethylformamide (DMF) could be photografted steadily on low‐density polyethylene (LDPE) film surface under UV irradiation. In short irradiation time (4 min) and at room temperature, high grafting efficiency (approaching 100%) and remarkable graft polymer amount (grafting percent is about 4.6%) was obtained. The possible reaction mechanism was based on the photosensitivity of DMF, which induced this photografting polymerization. This finding is useful to develop photoinitiator‐free grafting or photopolymerization system. Using SEM, special discrete globular structure was found on the MMA‐grafted LDPE film surface, and a possible model was proposed to interpret it.
