Butyl acrylate is polymerized in the living way under the irradiation of purple light‐emitting diode (LED) or sunlight without photocatalyst at ambient temperature. 2‐((Phenoxycarbonothioyl)thio) ethyl propanoate) is exclusively added and acted as an initiator and a chain transfer agent simultaneously in the current system. Poly(butyl acrylate) with well‐regulated molecular weight and relatively narrow molecular weight distribution ( Ð < 1.30) is synthesized. High conversion (>95%) can be achieved within several minutes. Polymerization shows oxygen tolerance. Near quantitative end‐group fidelity of polymer is demonstrated by 1 H NMR and matrix‐assisted laser desorption/ionization time‐of‐flight mass spectra.
